Hi,
It was a great experience for a first time Turkey visitors like us ( family of 5) to stay in such a easy accessible accommodation. We didn’t worry about the steep climb, the apartment was wonderfully clean and bright with day light. Heating system was amazing as we went in quite cold weather. The communications were easy with the host. Full access to everything, Taksim mosque was really 2/3 minutes walk and Istiklal street was next to Taksim Mosque , very good surroundings of course and safe area. There were needy people( not stubborn type though) under the apartment but they were not chasing at all, bless them.
Couple of things in the apartment that really bothered, the strong smell from apartment’s duct coming from bathroom side . ( might be it’s the whole building problem), second thing was limited hot water for shower . Only one person could have shower at a time . It should be upgraded according to the number of guests .
