Very nice and comfortable apartments I have ever lived in Istanbul. It is exactly like in the pictures, very clean and cozy. And - believe me - there is EVERYTHING you might need during the stay. All is taken care of! We got cookies, fruits when coming - owner and her mother is very thoughtful and caring.
On the drawbacks apartment has thin walls and you can hear neighbours quite well, but probably that is a general problem in Istanbul. But neighbours are ok, street is quiet, so no noise problem.
We loved it. I hope I get to live there again when I come to Istanbul.
