Apartment is great and the hosts are super friendly and helpful - even lent us umbrellas when there was an unexpected downpour.
Well situated for main tourist attractions, most of which are in walking distance.
Only slight niggle was that the apartment has seen some wear and tear, nothing major and remains excellent value for the price. Also, the walls are quite thin, we were fine but if you are a light sleeper this might be tricky for you.
Overall though we were very happy and would stay again if returning to Fatih.
