Istanbul is one of the world’s great cities — the only metropolis straddling two continents, with 2,500 years of layered history as Byzantium, Constantinople, and Istanbul. Four days is not enough to understand it, but it is enough to fall in love with it and to understand why people keep coming back.
Here is how to spend four days well.
Before You Arrive
Currency: The Turkish lira (TRY) fluctuates significantly. Use ATMs in Istanbul to withdraw cash at the interbank rate (far better than airport exchange counters). Avoid exchanging money before you arrive. Most tourist restaurants and hotels accept cards, but bazaar shopping and street food requires cash.
IstanbulKart: Pick up a rechargeable transit card from any metro station upon arrival (10 TRY for the card, then load it with credit). It covers the metro, tram, ferry, and bus at significantly lower per-ride rates than buying individual tokens.
Museum Pass Istanbul: At approximately €30 (price in TRY varies), the museum pass covers Topkapi Palace, Hagia Sophia (the museum sections), Dolmabahçe Palace, and several others for five days. Worth it if you plan to visit more than two of the included sites.
Day 1: The Old City (Sultanahmet)
Sultanahmet is the historic core of Constantinople and the most concentrated archaeological district in Istanbul. It could occupy a week of serious exploration; four hours covers the essentials.
Morning: Hagia Sophia
Start here before the crowds build. Hagia Sophia was the world’s largest cathedral from 537 AD to 1520 — built by Emperor Justinian, converted to a mosque by Mehmed II after the Ottoman conquest in 1453, secularised as a museum by Atatürk in 1934, and reconverted to a mosque in 2020. The building is open to non-Muslim visitors outside prayer times (check the schedule online — five daily prayers require temporary closure for tourists).
The interior is staggering: the 56-metre dome floating on 40 windows, the Byzantine mosaics partially visible beneath Ottoman calligraphy, the sense of 1,500 years of continuous religious use embedded in the stones. The upper gallery contains the best-preserved mosaics, including the famous Deësis mosaic (Christ flanked by the Virgin and John the Baptist). Allow 60–90 minutes.
Mid-morning: Blue Mosque
A five-minute walk from Hagia Sophia, the Sultan Ahmed Mosque (Blue Mosque, built 1609–1616) is the only mosque in Turkey with six minarets. The interior is decorated with over 20,000 hand-painted Iznik tiles in blue, green, and turquoise that give the mosque its name. Prayer times require tourist waiting — morning and early afternoon access is usually uninterrupted. Dress code strictly enforced: head covering for women, covered shoulders and legs for all, shoes removed.
Noon: The Hippodrome
The open space in front of the Blue Mosque was for a thousand years the Hippodrome of Constantinople — the civic and sporting centre of the Byzantine Empire, with a capacity of 100,000. Three ancient monuments remain: the Egyptian Obelisk of Theodosius (originally from Karnak, 1500 BC), the Serpent Column from Delphi (478 BC), and the Column of Constantine. Free, takes 20 minutes.
Lunch: Sultanahmet area
The restaurants immediately surrounding Hagia Sophia and the Blue Mosque are tourist traps. Walk three blocks toward Çemberlitaş and you find lahmacun (thin flatbread with spiced minced meat, rolled up with salad, €1.50–2) and pide (Turkish flatbread pizza, €3–6) at normal prices. Tarihi Kapalıçarşı Pide Salonu near the Grand Bazaar serves excellent pide in a no-frills setting.
Afternoon: Topkapi Palace
Topkapi Palace was the administrative and residential centre of the Ottoman Empire for 400 years. The complex is enormous — four courtyards, hundreds of rooms, and the palace treasury containing the Topkapi Dagger, the Spoonmaker’s Diamond (86 carats), and the throne of Ahmed I. The Harem section (separate ticket required, ~€10) offers the most intimate glimpse into Ottoman palace life.
Allow a minimum of two hours, preferably three. The views over the Bosphorus from the palace walls are exceptional. The Museum Pass Istanbul covers general entry.
Late afternoon: Grand Bazaar
One of the world’s oldest and largest covered markets — 61 streets, over 4,000 shops, and approximately 250,000 daily visitors. Don’t try to shop seriously on the first visit. Walk through to orient yourself: carpets in the old inner bazaar, gold and jewellery on Kalpakçılar Caddesi, leather along the outer sections. Prices are negotiable — start at 40–50% of the asking price.
Evening: Beyoğlu and İstiklal
Cross the Galata Bridge (walking, watching fishermen line the railings) to the European New City. Walk up to Galata Tower (€8 to climb, good views, can skip if time is short), then along İstiklal Caddesi — Istanbul’s 1.5km pedestrianised shopping street, always crowded, always alive. Dinner in Beyoğlu: balık ekmek (grilled fish in bread, €3–4) from the boats at Eminönü waterfront, or meze and raki at a meyhane (traditional tavern) in the side streets off Nevizade Sokak.
Day 2: Bosphorus, Asian Side, and Bazaars
Morning: Bosphorus ferry crossing
Take the regular commuter ferry from Eminönü to Kadıköy on the Asian side (€1–2 on the IstanbulKart, 25 minutes). This is genuinely one of the best value activities in Istanbul — the Bosphorus from water level, with the European skyline of Topkapi and Hagia Sophia behind you and the Asian shore emerging ahead, is spectacular and costs almost nothing.
Kadıköy: Istanbul’s coolest neighbourhood
Kadıköy is the food and café district on the Asian side — less touristy, younger, and more creative than Sultanahmet. The Kadıköy market sells excellent produce, spices, and Turkish cheese. The streets around Moda are lined with independent cafés, record shops, and restaurants that feel like real Istanbul rather than performed Istanbul. Have breakfast here (menemen — scrambled eggs with tomato and pepper — €3–4, plus Turkish tea from a çaydanlık).
Afternoon: Egyptian Spice Bazaar (Mısır Çarşısı)
Back on the European side, the Spice Bazaar near Eminönü is smaller and more manageable than the Grand Bazaar, with excellent saffron, dried fruits, Turkish delight (lokum), and spice blends. Better for shopping than the Grand Bazaar for first-timers — fewer stalls, less pressure, better quality control at the reputable shops.
Late afternoon: Süleymaniye Mosque
The mosque built by Suleiman the Magnificent in 1557 (architect: Mimar Sinan, who may be the most accomplished Islamic architect in history) is less visited than the Blue Mosque and more architecturally significant. The hilltop location provides the best panoramic view of the Golden Horn. The adjoining külliye (mosque complex) includes a hamam, medrese, imaret (soup kitchen), and Sinan’s own tomb in the gardens.
Evening: Bosphorus cruise
Take the €2 commuter ferry from Eminönü up the Bosphorus toward Anadolu Kavağı and back. This is the 90-minute Bosphorus public ferry route — a fraction of the cost of tourist cruises, the same view, and full of locals commuting home. If you want a longer sunset cruise, book a small-boat tour (€15–25) from the Eminönü docks.
Day 3: Hammam, Dolmabahçe, and Balık Ekmek
Morning: Traditional Hammam
Book an appointment at a historic hammam operating for centuries — Çemberlitaş Hamamı (1584, designed by Mimar Sinan, €45–65 including scrub and massage) or Cağaloğlu Hamamı (1741, €55–75). Both are excellent, operating in their original Ottoman bathhouses. Arrive 30 minutes before your appointment.
The hammam experience: undress in a private changing room, wrap in a peştemal (cotton wrap), enter the warm outer room (soğukluk) to acclimatise, proceed to the main chamber (hararet) — a marble room with a central heated stone platform (göbek taşı), domed roof with star-shaped windows. Lie on the marble while an attendant (tellak) scrubs you with a kese (rough mitt), washes your hair, and gives a foam massage. Takes 60–90 minutes and is genuinely restorative.
Mid-morning: Dolmabahçe Palace
The last Ottoman Imperial Palace (1856) on the Bosphorus shore represents a deliberate Westernisation — built in European Neo-Baroque style at enormous expense, with the largest chandelier ever made (4.5 tonnes, gift from Queen Victoria), a ceremonial hall with a 45m ceiling, and interiors of extraordinary opulence. Atatürk died here in 1938.
Entry and tour approximately €20. The palace is too crowded for solo exploration — guided tours depart every 30 minutes and are worth the structure.
Afternoon: Ortaköy and the Bosphorus Bridge
The neighbourhood of Ortaköy sits directly under the Bosphorus Bridge — the suspension bridge connecting Europe and Asia. The waterfront square has a small baroque mosque photographed against the bridge backdrop, excellent kumpir (stuffed baked potato, €4–6) and waffle stalls, and a fish restaurant terrace overlooking the strait. A pleasant afternoon of walking and eating.
Evening: Beyoğlu dinner
The Balık Pazarı (fish market) neighbourhood in Beyoğlu has the highest concentration of meyhane (traditional meze and raki taverns) in Istanbul. Nevizade Sokak is lined with them, spilling tables into the street in good weather. Order meze (cold appetisers — haydari yoghurt dip, stuffed vine leaves, smoked aubergine, white bean salad) followed by fresh fish grilled to order. Budget CHF 25–40 per person with raki.
Day 4: Princes’ Islands and the Grand Bazaar (Shopping)
Morning: Büyükada (Princes’ Islands)
Take the morning fast ferry from Kabataş to Büyükada — the largest of the Princes’ Islands in the Sea of Marmara, 45 minutes from the city (€5–8 each way). The islands are car-free, navigated by horse-drawn carriage (phaeton) or bicycle, lined with Victorian-era Ottoman summer houses in wood, and offering a completely different sense of Istanbul — quiet, fragrant with pine and bougainvillea, and surprisingly undiscovered by most visitors.
Hire a bicycle (€5–8/hour), cycle to Yücetepe Monastery on the hilltop for panoramic views, and eat fresh fish at one of the waterfront restaurants. Return ferry leaves for the afternoon.
Afternoon: Grand Bazaar revisited (serious shopping)
Now that you know where things are and what they cost, the Grand Bazaar is more manageable. The best things to buy: Turkish carpets and kilims (established dealers will have documentation; avoid street vendors with “special deals”), Iznik-style tiles and ceramics, copper and brassware, Turkish delight (buy from Hafız Mustafa chain, not random kiosk stalls), saffron (check for pure vs. dyed imitation), and leather goods.
Evening: Farewell dinner with Bosphorus views
Splurge on a Bosphorus-view dinner at a fish restaurant in Arnavutköy or Bebek — the upscale European Bosphorus villages north of the centre. A ferry (IstanbulKart) or taxi takes you there; the setting, with fishing boats in the strait and the Asian hills beyond, is the best final memory Istanbul offers.
Istanbul Practical Notes
Safety: Istanbul is very safe in the tourist areas. Normal urban precautions apply — keep phone and valuables secure on public transit, be aware in crowded bazaars.
Water: Tap water in Istanbul is technically safe but heavily chlorinated. Buy a reusable bottle and use refill stations, or buy bottled water.
Tea: Accept every glass of çay offered to you — it is genuine hospitality, not a sales tactic. Refuse it and you create an awkward moment. Drink it and enjoy; it is excellent tea.
Haggling: Expected at bazaars, not at restaurants or supermarkets. Start at 40–50% of the asking price, and if the vendor meets you at 60–70%, that is a fair deal.
