We had a great 3 day stay at Heinz's place. The apartment is clean, spacious and perfectly located for exploring Berlin. The Holocaust Memorial is right next door with the Brandenburg Gate, Reichstag and Potzdamer Plaza within a 5 minute walk. I highly recommend the Vintage Bikes Cafe around the corner on Wilhemstrasse for brunch and the restaurants on Freidrichstrasse by the River. We would definitely stay here again. Thanks Heinz.
