Kollwitz Mansion is a showstopper. We were 4 people, using both bedrooms and the fold out couch. Everything was comfy and beautifully decorated. The neighborhood is fantastic, just a 5 minute walk to the S-Bahn and the U-Bahn. And so close to many fantastic restaurants. A big REWE grocery store is also just a couple of blocks away. Very much recommended this beautiful apartment. Tina was wonderful, meeting us and responding to messages.
