We stayed in Seda's place and really enjoyed it. We would stay there again. The location is terrific, being right at the Galata Tower. I loved sitting on the couch and reading in the morning with the view of the tower on one side and the Bosphorus on the other. The apartment works well for numerous people, as there are two bedrooms, each with a double bed, and the living room, which easily can be closed off as its own room, with nice couches. The terrace view is lovely.
Seda was very helpful and responsive to texts, which is how we communicated, and she was flexible on meeting and check out times, which was so helpful.
The few things that were not absolutely perfect were barable, and maybe have been mentioned already.
