I booked this flat for my cousin with her little son. They found the flat comfortable and the location was really great and very central in kadiköy.
The neighbors were very loud. In the night at 4:00 came neighbors drunk and very loud at stairs.
The heating was defect but the host was very responsive and easy to reach.
For passengers with heavy baggages not recommended. The stairs are a bit tiny and the flat is on the 4th floor.
