It’s a basic, clean and very functional apartment, an studio, with a double bed and a sofa in which can sleep one child or one (not an extra large) adult.
Batuhan was fast to respond and quick to make accommodations for us, always efficiently and with a good will.
The apartment is perfectly located in the heart of Beyoglu, next to the the Tramvam station of Findliki, the Kabatas pier (to take the ferry to Üskudar and to the Princes Islands) and the Taksim lift. It’s a walking distance to Taksim square, Çukurkuma, Istlikal street, etc.
One little inconvenience might be (be aware) that the apartment has only a small low window with not a good view.
I general, I loved my stay and I would come back on a heartbeat!
