Definitely recommend! Host(s) we’re very responsive and helpful (kindly carrying my suitcase up the hill and up the stairs - thanks, Can!). Apartment was clean, well maintained, and the toilet and shower work well. Close to everything you need, including a pharmacy. Listing mentions it being in a ‘lively district’ so I was concerned about noise, but the apartment/building was very quiet.
Note that Galata area is essentially a hill, and to reach the apartment requires an uphill walk on that street (dead-end so you can’t come in from the top). Those with mobility issues may find it challenging.
We arrived early so host suggested a hotel with coffee shop where we could store our luggage until checkin. Something to keep in mind - luggage is not stored in a locked area, and to get to the apartment requires a walk downhill on the cafe road, then a crossover to the apartment road, and an uphill walk on that one. (Thanks again, Can!) But a nice place to relax and enjoy a coffee.
