I have booked a stay in Fuad's place for my parents, as they were coming over for a visit. They are pensionaries and need peace and quiet, and are not used to staying in unknown places. Fuad made sure to answer all of our questions very promptly and made my parents feel very welcome, and very comfortable.
The flat is spacious, typical Berlin flat with high ceilings. Location is good, nearby a few tram lines that can get you to different spots in Berlin. Few bigger shops in the vicinity, and a nice focaccia place 5 minutes down the street.
