Easy-to-find location with a store and a coffee shop downstairs. For the ones coming by car: there are 2 private parking lots next to Babel, very cheap.
The building is 5 mins walk to Taksim street where you can do shopping, eat, exchange money etc
Also there is a 10 mins walk to T1 tram that goes to all main attractions in Sultanahmet.
The apartment is very clean, it has anything you need. The bed is extremly comfortable and there is always hot water.
