Had a great stay at Heinz' apartment. The apartment is centrally located in Berlin, close to the metro, Brandenberg gate, Reichstag, and the Jewish memorial. We had a total of 4 people and the apartment had plenty of space (3 bedrooms) for all of us, plus a lovely living room, dining room, and kitchen. It is also about 2 blocks away from a grocery store and the Mall of Berlin. Would recommend this place if you are looking for a central Berlin location.
