The hotel was very good and clean. The bar on the top floor has a great view of the old city, and the bartender is extremely nice and speaks very good english as well. The breakfast given free of charge was good. I had originally reserved a room with just one large bed in the basement, but they offered to let me stay in a 3rd-floor room with two smaller beds, which was much better. The location, though, is the best aspect. It is right near Sultanahmet, but also off a side road so that it's not too loud or bright at night.
The one issue I had is that, when I reserved the room, I thought I was getting an individual, private airbnb. The room and the whole complex is in fact part of a hotel. However, I don't think they were intentionally deceiving me or anything - I think I just misunderstood the initial airbnb post, and also there may have been a language barrier. In retrospect, the photos also clearly show it is a hotel room. So that was my fault. But make no mistake, I have no regrets staying here - it was very wonderful.
