My wife and me have been living in the apartment for one month. And I can say that it was certainly the best accomodation I had on AirBnb ever. The apartment located is very close to Karakolhane Cd. with multiple cafes. Marmaray station, metro station and ferry station are also in walking distance. Despite this location the apartment is very quiet. The apartment has a beautiful interior and everything you need for life.
But I would especially like to mention the hostess, Demir. She is extremly kind, responsible, responsive and easy to communicate. All our requests found a response (additional cleaning services, heating and furniture issues). So it was a very pleasant experience. I highly recommend Demir.
