Ross and Sonja's apartment is wonderful. It is well furnished, clean, and fairly convenient. We always prefer to stay in Neubau, so the 48A bus is very familiar. Ross and Sonja were very responsive hosts. They answer questions quickly and have a seamless check in and check out process. They moved quite swiftly to resolve a couple of minor plumbing issues in the apartment at the start of our stay. I would certainly recommend them to other travelers.
