We just stayed for one night, but we found it perfect for our needs - very clean, beds comfy, decorated to a good/modern standard, breakfast was good., staff were helpful. Didn't get to eat in the restaurant in the evening but the menu looked interesting, and would have liked to try it. Not in the middle of the Old Town but very close to a tram stop and not a problem at all to get into town - only a few stops on the tram to Bismarkplatz.
