For me, one of the main criteria choosing the apartment was that it's on a flat ground - Istanbul can be quite hilly, and my previous airbnb flat was mid-hill, so this was important to me. And the elevator was a nice add. The flat is at a very lively area, lots of bars, restaurants etc, which was nice - even if quite noisy, if you're a light sleeper. Really liked the bedroom/living room area in the flat, and the bed was comfy. Would probably rent again.
