Are you looking at Frank's home here and wondering should I stay here? The answer is yes. It's better than you are imagining and Frank is at least 3 times cooler than your best guess. Frank has created an amazing home/museum/art space. He is a super friendly host, and his Saturday night salon event in the front room is my favorite Berlin memory. I felt very safe as a solo female traveler with Frank. You get a key to your room and the building, towels, toiletries, and a cozy room with a great heating system. The apartment is right around the corner from the Schönleinstraße U-Bahn station. Hot tip: You MUST come to one of his Saturday night events, even if you aren't lucky enough to stay on a Saturday. I would highly recommend Frank's home.
