The host has been flexible with the arrival time and he has been kind to us. The apartment is located in the turistic center of Istanbul, very close to Hagia Sofia. However, the apartment was quite dirty when we arrived and some basic kitchen elements were missing.
The curtains are really cheap quality, they let through all the light. The walls are incredibly thin, you can hear everything from the neighbors.
The apartment needs some maintenance in general - the front door was always a struggle to open, the door of the balcony got stuck and couldn't be opened at all, the towel hanger fell off after first use. The washing machine was very difficult to use.
I give it three stars because it is a cheap accommodation.
