The apartment is great if you want to have a nice place in Sultanhamet. You can get to the Blue mosque in 5 minutes.
The place is very-very clean, all furniture and household appliances are good.
The view from 3 floor is amazing (Bosphorus and seagulls). Supermarkets and cafes are very close.
The only thing that should be noticed: the mosques are very close, so be ready to hear a muezzin at 7am)
