Istanbul rewards the visitor who treats it as two cities stitched by water rather than one checklist. Three days catches its structure: the imperial plateau of Sultanahmet on day one, the hill-town charm of Galata and an Asian-side afternoon on day two, and the strait itself on day three at the hour the ferries turn amber. Prices sit far below western Europe — about halving on arrival — and its transit is honest: a rechargeable Istanbulkart works on trams, ferries, metro, and funiculars alike.
Where to sleep, by preference
Sultanahmet sleeps cheapest and closest to the headline sites (walk-to-everything; 45–75 euro for characterful small hotels), but its restaurants price like exhibits. Karaköy–Galata (55–90 euro) is the better general base: connected to the tram line, thriving café life, and evening streets with residents rather than tour groups. Families wanting apartment-style rooms find them at Kadıköy prices with Galata quality at the Asian shore (50–80 euro) — a base that still reaches the European side in fifteen ferry minutes. Book with the refund-and-recheck discipline covered in our booking guide; Istanbul’s rates move with Turkish holidays rarely far away.
Day 1 — the imperial plateau, north to south
Start inside the Blue Mosque before the tour coaches land (visit outside prayer hours; free with modest dress), cross to the Hippodrome, then Hagia Sophia — buy the first entry slot of the day, since the queue shape matters more than the ticket type. Lunch on the plateau’s side streets: a doner plate at 5–6 euro, ayran included. The afternoon belongs to the Basilica Cistern (book the first slot after 9:00 for mirrors-empty water and columns) and the Grand Bazaar on the way back — the bazaar’s arithmetic favours early exits: window-shopping is free and the souvenirs worth carrying (ceramics from İznik workshops, saffron from spice-source stalls) price better at the two workshops near the cistern exit than inside the bourse itself.
Day 2 — Galata hills and the Asian shore
Morning: climb from Karaköy through the craft shops of the hill to Galata Tower’s platform (book the first hour) for the Golden Horn panorama, then walk İstiklal Caddesi’s side-street network — the Asmalı Mescit lanes and the flower-market’s honest cafés — toward Taksim. Lunch in Beyoğlu’s çesme kebab counters or a 40-year-old fish-sandwich stand (6 euro). Afternoon: take the Kadıköy ferry from Eminönü or Karaköy (compare: the commuter ferry is 1 euro; the sightseeing cruise is 25) and give Kadıköy’s Moda quarter its due — bookshops, the bull statue’s coffee lanes, and dinner at the market that feeds this city after work: Adana kebab at 8–10 euro where locals queue, not where tour buses stop. Return by ferry at night; the skyline crossing is the city’s best 20 minutes.
Day 3 — the water, properly spent
Choose one palace and one strait. Dolmabahçe Palace (harem-and-hall tickets 25–45 euro; guided-format timing enforced) dazzles in the morning half; alternatively Topkapı’s courtyards in the first hour beat its afternoon queues. Then board the 13:35 short-circle Bosphorus ferry or the commuter service toward Anadolu Kavagi — both price like commuter tickets and both deliver the same shoreline the lunch cruises sell. Alight at a strait village for grilled fish tables right by the water (12–18 euro), return with the crowd’s daylight dying behind Rumeli Hisari. Istanbul’s final evening: a meyhane in Beyoğlu or Kadıköy where meze arrive as they are ordered and the bill lands near 20 euro with raki included.
Money shape, per person, three days
- Lodging: 2 nights x 70 euro shared basis = 140 euro (about 70 each)
- Food: 20–28 euro per day (breakfast from simit carts and börek counters costs 2 euro; street-culture meals dominate)
- Istanbulkart + transfers: 8–10 euro, including airport connections on the M11 metro
- Entries: Hagia Sophia 25 euro, cistern 28 euro, one palace — keep to two ticketed wonders; the city’s soul prices free
Core: about 250–300 euro per person excluding flights. That places Istanbul among Europe’s best-value capitals — a pricing that runs opposite to Rome‘s and closer to the value-density explained in the Prague budget.
Traps and two honest warnings
Restaurants without printed prices around Sultanahmet’s square (menus with the day’s currency handwritten at the table’s edge are where the euro vanishes), the shoe-shine-and-brush scam that starts with a dropped shoe, and nightclubs whose “cultural night” charge arrives unpriced at the door — the last belongs to a specific district and deserves skipping entirely. The two warnings: Friday-midday prayer hours close mosque visits (plan the cistern or palace for that slot), and the tram works but the city’s real distance is measured downhill — comfortable shoes beat any transport plan, the same walking arithmetic that the Lisbon plan is built on.
When to go
April–May and September–October deliver the strait at its clearest and temperatures made for walking. Ramadan changes rhythms (evening iftar crowds are a feature, not a problem); winter costs a shade less and the city wears its indoor smokiness, which suits the cistern-and-museum route. In any season, Istanbul pays back the traveller who crosses the water at least once a day — its ferry arithmetic is the destination’s most undervalued commodity.
