Martin was an amazing host and provided us a great stay in Berlin. His apartment is in a very central part of the city and easily walkable to sights like the Reichstag or Checkpoint Charlie. The apartment is clean, comfortable, and spacious. Martin was very friendly and provided numerous recommendations for food and activities in the area. He was also able to accommodate us with our train leaving after the check-out period. I would definitely recommend this apartment to anyone who is looking.
