Great apartment!
Pros:
+ Location. Located in a great area of Besiktas. Lots of cafes and stores with good prices. The apartment itself is in a quiet area without tourists.
+ View from the window + access to the roof.
+ Fully furnished apartment. There is everything you need to live. Full kitchen, cabinet, large bed in the bedroom, space for relaxation, sound system with AirPlay, projector.
+ Great host who showed and told you everything and answered any questions you might have.
The only minus was the hill! After a day on foot exploring Istanbul, very lazy to go up to the apartment. Well and the cab drivers very often cancel the order when they see where they need to go.
