We had a wonderful time in Berlin. Robin has always been helpful and kind even though he was not in town. Gerlinde, Robin's friend that received us on the apartment did a very good job and even helped us when we forgot the keys inside. The apartment is very comfortable and spacious. We were with our 2 kids and it was fine for them too. The building has an elevator which facilitated our life a lot! The location is just perfect, the neighborhood is trendy and quiet at the same time. Lots of options of restaurants, cafes and stores around. I highly recommend!
