Hikmet was a great host, friendly, positive and always willing to help. He organised transfer, and offered us a delicious breakfast on the terrace the next day, which was really nice.
The apartment looks just as pictured, it's comfortable and clean. There is everything for living. It's basement, but in summer it's even better - it doesn't heat too much that way.
The location is nice as well; streets in the Old City are quite steep, though, anyway, you can reach Sultanahmet, where the main tourist sights are located, in several minutes.
So, everything makes this places worth to stay in.
