I went to Nick's appartment for 5 nights with a friend and her mother. The flat is really huge with high ceiling, it is much better than on the photos!! It is very well equipped (hairdryer, cooking ustensils etc.) and the bathroom is also large. The flat is located in a calm street and is near Taksim Metro Station (6 minutes by walking). The neighborhood is also great with some nice restaurants & cafes (Van Kahvalti, Miss Pizza etc). As for Nick, he was very reactive. We recommend Nick and his flat to anyone !
