Martin's place was perfect! It was quiet there but well located- very easy to access the transportation system as well as a 10-15 minute walk to the Mall of Berlin, Topography of Terror, Potsdamer Plaztz, and Checkpoint Charlie. His place was in a quiet neighborhood and he provided plenty of tourist pamphlets and little things like a few bottles of water and body wash. I would definitely recommend booking one of his 3 apartments! He's very friendly and helpful.
