The host was actually very nice and easy to communicate. His apartment is also good and in nice and quiet location, near to Marmaray and Metro (like 5 minutes on foot). Maybe the only and big problem for me is that the room was dirty (maybe for other people not that dirty). The picture of the room for guest didn't match the real one. So after I checked in and saw the circumstances, I decided not to stay there. For that I lost some money:(
