Nice apartment, clean, fresh. Cozy living room with great view (Galata tower, some of Fatihs great mosques). Very quiet sleeping rooms in the back, in the frontside sleeping room you hear the Muezzin´s prayer calls, but the street itself is quiet at night. The kitchen is sufficient for breakfast, but not more.
The flat is great for four people. It can theoretically accommodate six people, but that would feel a bit cramped, imho.
Great location at a very nice street, lots of small eateries, cafes and small shops. Very central location, easy to reach tram and subway. Easy to reach both Sultanahmet, Istiklal Caddesi and Bosporus ferries.
Some small items lacked when we arrived, but the host was quick to fix them.
Easy communication with the host.
