There was a problem with the heat/hot water in this unit, so Ralf informed us when we arrived that we were going to stay in a larger, 1-bedroom on a higher floor in the same building. I thought it was very nice and professional of him to arrange for that in advance of our arrival. I can't comment on this unit because I never saw it, but I can say that Ralf and his colleagues were very responsible and responsive hosts, that the unit we stayed in was in good condition with a great view of the city, and that the building itself is secure and updated. We also loved all of Ralf's restaurant recommendations!!
