Heinz dosn't exist! This is a cheap hotel in the center of Berlin. It has nothing to do with the idea of Airb'n'b. Nobody exepts tourist lives in the apartment. But besides that its a OK cheap spacy hotel apartment in tahe center of Berlin. I won't use it again, because I finde area boring. I would rather sleep in Kreutzberg or Prinzlauer berg. If you want to live next to the american embassy, brandenburger tor and "unter den linden" you are in the right spot. After 17:00 its quit borring.
