Unfortunately I didn't meet Daud personally but he was a great host and responded to all my questions prior to and during our stay.
Place looks exactly as pictured. We had everything we needed for a comfortable stay. I liked that the place was not cluttered and had large windows that let in fresh air and light! Location was awesome,just 2 minutes walk to the U bahn station. There were bakeries, restaurants, markets, bars around - pretty much and everything you need within walking distance.
If I'm back in Berlin I would definitely stay there again.
