Safa is a helpful and friendly host, it was kinda quiet at night, the only noise came from the guests from the hostels nearby sometimes, although taxim is 5min away. The only problem there was that there surely was mold, not to see but to smell, but that's a problem which occurs often talking about Turkish houses. It was clean and all things you need for your stay were provided. Also there are two 24/7 markets on the same street. The street seemed to be mostly inhabited by arabic speaking people.
