My flat is in the heart of the city, Besiktas!
Bus station that you can go everywhere in Istanbul is in 3 minutes, ferry is in 5 minutes, a lot of popular bars, cafes, restaurants and shopping stores are in 5 minutes walking distance. There is a grociery store just across the apartment which you can find anything you need.
There is a king size double bed in the room which i will provide with clean sheets. It is especially very good for couples. There is also wifi in the house.
