I hope Gerhard's apartment is available every time I visit Berlin! I had the good fortune to stay there for over 3 weeks and felt comfortable and relaxed the whole time. The apartment is one of the most pleasant spaces I've stayed in -- light and airy with all the amenities needed to make myself at home, plus it's in a terrific neighborhood location for exploring the city by foot or public transit. To top it off, Gerhard is a truly amazing host. He welcomed me at the train station, was quick to respond to my questions, and provided me with some of the best tips for things to see/do/eat. I wish I could've stayed longer!
