Constantinople

The alternatives, priced for four of us with luggage — the question came up at the family meeting, so here is the answer rather than a shrug:

• Welcome Pickups — prepaid, meets you inside arrivals, tracks the flight, an hour of free waiting. €38 for the minivan (up to 8) against €32 for the sedan (up to 3), so the size we actually need costs almost nothing extra.
• Yellow taxi from the official rank, on the meter — about ₺2,600 (~€46), 50–65 minutes. A standard cab is tight for four with bags, so ask the marshal for a large one. Card payment is mandatory at licensed ranks: confirm kredi kartı before boarding, and ignore anyone offering a ride inside the terminal.
• Blacklane, the private-car service — worth knowing that Business and First Class carry only 3 passengers and 2 check-in bags, so four of us need Business Van/SUV. No fares are published; they are quoted at the time of booking.
• Havaist coach — about $10–12 a head, but 90+ minutes with luggage handling, and its direct old-city route has been on-and-off through 2026.
• Metro — cheapest by a distance, and two changes with bags. Not after a transatlantic day.

Hop on at Sultanahmet and Galataport is about four stops and one bridge away — handy on ship days when we're traveling light. Tap in with an Istanbulkart or a contactless credit card.

The best version is a loop: Marmaray under the water to Üsküdar, tea and a wander on the Asian shore, then a ferry back across the top with the whole skyline in front of you. Train under, boat over — two continents, two crossings, one afternoon.

This is the everyday version of the Bosphorus cruise, for about a dollar. It pairs with the Marmaray loop above, or stands alone as the Wednesday "set foot in Asia" trip.

Taxis are the move whenever there's luggage (embarkation day) or a cross-town target like Chora or the Espressolab Roastery. Inside Sultanahmet, walk.

One card can cover all four of us. Tap it once per person boarding the same tram, ferry or metro — it is routinely used this way for groups of up to five, which saves buying four cards at ₺165 apiece. Two caveats worth knowing before we rely on it: the transfer discount only applies to the first tap, and while every guidebook describes the practice, we could not find an official İBB page that states the limit. Carry a spare card rather than betting the whole group on one.

Even riding everything on this list, a full transit day runs a few dollars a person. Fares last checked July 2026 — Turkish prices move with inflation, so expect some drift by December.

The single most awe-inspiring building of the trip. Now an active mosque, so we dress respectfully. Our tickets are bought in advance and the guide works the timing around prayers.

On the hours: the mosque itself takes visitors from 09:00 until midnight, but the paid upper-gallery route closes earlier and no authority publishes when — the figures in circulation run from 17:00 to 20:30, and several of them turn out to be a different building's timetable or the old museum's, retired in 2020. Sunday's visit falls in the early afternoon, so none of it touches us; anyone going back independently should aim for the middle of the day.

Good to know: Hagia Sophia is undergoing a major multi-year dome restoration, so expect scaffolding inside and some obstructed views up into the dome. It stays open to visitors throughout — and December's thin crowds are a real upside. The separate History and Experience Museum behind the main building (opened 2023, in the old Land Registry Office) holds original mosaic fragments, early blueprints and digital reconstructions of the dome, which is useful precisely while the real one is behind scaffolding — though it sells its own €25 ticket and is not covered by the mosque's.

Both fall on the guided day, a few minutes apart across the Hippodrome. Free to enter; just respect prayer times and dress code.

We cross it every day without noticing, and it is the first ground the guided day covers. Costs nothing, takes minutes, and the carved base repays a slow lap.

The Harem is bundled into the main ticket; Hagia Irene is not — it's a separate ₺1,050 (about €19) if anyone wants the bare Byzantine church in the first courtyard. Winter hours are short and dark falls fast, which is why this leads Monday morning.

Just steps from Hagia Sophia and gloriously warm and dry — a perfect December stop. Its ownership is still being fought over: the handover to the Directorate General of Foundations was carried out on 2 June 2026 and suspended by the courts two days later, with the appeal still open. Prices did not move through any of it, and the place never stopped selling tickets — our guide has already bought ours for Sunday morning. If anyone wants a second one without the crowd, Şerefiye and Binbirdirek are two smaller Byzantine cisterns a few minutes away in the same quarter.

Out by the Theodosian Land Walls, so the two pair naturally — the city's greatest art beside the walls that guarded it for a thousand years. The strongest candidate for Wednesday if we strike out on our own — and Balat, the old Jewish quarter of pastel houses and tea rooms, is the next neighbourhood over, which turns a taxi out to one church into an afternoon.

A labyrinth, and cosy in winter. Haggle politely, accept the offered tea, and don't be afraid to get lost.

Viking's Wednesday tour is called Old City Walls, Spice Market and Rüstem Pasha Mosque — the Spice Bazaar is in the title, which is why we took it off the Sunday itinerary. A winter Bosphorus cruise has heated indoor seating and the best skyline views — an easy, warming way to see the city from the water.

If we buy spices to bring home, ask the seller to vacuum-seal them at the stall — the same request works in the Kuşadası bazaar.

If we have an hour to spare, the view from its terrace is the best in the old city.

The one thing in Constantinople that isn't a building you look at. It sits on the Hippodrome side of Hagia Sophia, roughly five minutes from the hotel door — but it takes a couple of hours, it is not cheap, and it only happens if somebody decides in advance. Cağaloğlu Hamamı (1741, ten minutes north, packages from about €95) is the other historic option. For scale, Viking sells a bath-and-tour afternoon on the 23rd at $174 a head — booking one of these directly is the cheaper way in, and the hotel days of the 19th to the 21st are the easier window for it anyway. Nobody has to; it's here so it can be asked.
