The flat is exactly as in the pictures. The location is very good and the communication with Gokce was prompt and easy.
One drawback is that there is neither a window nor a vent in the bathroom and there are also slight mold traces of a water leakage issue. It didn’t disturb us greatly as we were out all the day and Gokce informed us that it will get fixed asap.
So overall I recommend Gokce’s flat for a nice stay in Istanbul.
