I stayed 8 nights at Howy's place with my girlfriend and we both loved it! It was a short walk to the the subway which could take you to the middle of Berlin. Howy was always available to answer questions via AirBnB, otherwise we only saw him when we arrived and not again after. Everything was clean and worked the way it was supposed to! The only thing to note is the stairs to get to his place. We were sweating when we got to the top but it was a great way to burn off some of that beer ;). Loved the place and would stay there again if we get the chance
