The apartment is located in a very nice place close to the historical places and so close to the public transport (10 min). In addition it was in a friendly environment with a lots of Cafe or shops.
There was the same apartment and rooms and totally there was no differences between ad and the facilities.
Mehmet is a very nice person and he can speak English very well, in addition you can ask any information that you need from him.
If I will travel to Istanbul I will stay in his apartment again and I will recommend this apartment to anybody to stay there.
