If you are looking for a room for a few days, this is perfect. the location is great and you are close to everything. The only point which is really a dealbreaker in my opinion is, that the wall to the next apartment is like non existant in terms of noise. If you want to sleep and the kid or an adult walks next to the wall it feels like the person is literally walking next to your bed and through your room.
Besides that there is nothing to complain about and we really enjoyed the stay. As I said, if you want to stay for a few days in Instanbul, this is the place to be. The host is friendly and everything worked smoothly.
