Stayed there in May 2010 for business on my first visit to Black Forest area in Germany. Very conveniently located - short walk from Train station. Very reasonably priced. Excellent view of the hills and the forest. A very large green space and gardens in the vicinity and a cable car to take people up the hills make it an excellent location.
Stayed in a standard room which is so large and would be called a Junior Suite in most other European cities. Modern rooms too.
As the hotel is integrated into a commercial down town development, it is laid out very strangely - access from the street is tricky, had to ask people where the entrance was. The restaurant is on the first floor, and can be reached only after a 2 min walk through winding corridors.
Very friendly and efficient staff - eager to talk about the town. Encouraged me to do some neighbourhood shopping in the 1 hour of spare time I had with helpful tips.
Would definitely go back there and if possible take my family on my next visit.More
