Clean, well kept rooms. My shower did flood the bathroom floor the first time I used it (the drain was blocked), but they arrived pretty quickly to fix it.
The staff were pretty friendly and helpful. However they didn't follow through, even after telling me they would, on a couple of requests (very minor ones) that I made.
The restaurant attached to the hotel serves some very nice food, The sauce for the Viennese Bread Dumplings was very, very nice.
