I had a wonderful stay at Gerhard's apartment. His son met me at the train station and we walked to the apartment. The apartment is located in a nice and quiet area. There were several buses and train stations nearby so it was very convenient to get around. The apartment itself was well equipped and cozy! I would recommend it to anyone looking to stay in Berlin. Gerhard always made himself available to answer any questions. He also gave so many suggestions/recommendations. He truly is a super host!
