This hotel has a lot going for it - a super location, efficient service and friendly staff, plus the rooms are well-appointed and spotlessly clean.
However, we each had rooms overhead the restaurant terrace which meant that we had to choose between a hot room with the windows shut or a noisy room with the windows open! Also (and unusually for German hotels), the floors were wooden as opposed to concrete - which meant we could hear people creaking around all night.
We aren't fussy eaters or tight fisted gits, but we found the restaurant menu to be limited, expensive and a trifle pretentious. We instead opted for the fabulous eaterie across the road which had more atmosphere, an earthier menu and keener prices. Similarly, the bakery next door does a very good morning coffee and pastries!
As with many boutique hotels, we felt that this was perhaps a case of "style over substance".
