Starting with the positives - great location, everything is conveniently located - Blue mosque, Hagia Sophia, grand bazaar etc.
We had a negative experience because of the AC not working. It was 40° degrees and the AC stopped working on the first day at 12 am. We kept the windows open for some air but the place is so close to the mosque that you wake up at 430am with the Azaan. So we didn't get any sleep on the first day. The next day morning the hotel owner was prompt to help fix the issue. They gave us another room and helped us move to the room. The next day almost at the same time the AC stopped working even the other room. When I informed the hotel manager (who works there) she was really upset with me and did not communicate properly. We again moved rooms at 2 am. By the end of it we had little to no sleep for two days ( add jet lag on top of that) we were exhausted.
