Stefan was very, very welcoming and very kind. He was eager to ensure you had a good time, by giving recommendations, suggestions, and invitations to things he thought I might enjoy. The availability of the bike was perfect - I cannot emphasize ENOUGH how great it was to have a bike to get around Berlin. The room is lovely, and the location is ideal - a short walk from many great bars and clubs, and close to the U-Bahn station as well. I would highly recommend Stefan!
