We had a great time in the apartment. It was rather spacious and functional. The place was nice and clean with sufficient utilities. Some stuff was broken or dated, but Yaz pointed these things out very openly with us which was nice of him. Yaz was also very kind and provided us with all sorts of tips and advice for our holiday in Berlin. The restaurants and bars he recommended were great! Don't expect a 5 star luxury hotel though. But for the price of the apartment it was really great, especially if you are out much and don't intend on staying there for many hours during the day.
