The building is quite quirky, which can be a good thing if that's your thing. The location is excellent, the room is big and spacious (albeit being old). We had a two nights stay and the first night and day the electricity was out. Which can be very annoying in Istanbul because the AC was out and the top floors can get pretty warm even during the night. The elevator was not working so the 5th floor wasn't very ideal. Luckily we were busy and outside almost the whole time, otherwise the stay would have been quite a bad experience. The team was responsive to messages, but they didn't give me the impression that they were too concerned about our experience
