Generally helpful, extremely well located in a nice part of the city, and immediately adjacent to the eponymous Opernhaus. The staff were friendly, efficient and all around helpful. The selection of local products for e.g. alcohol, lemonade etc. is also worth appreciating. Rooms are decently comfortable for one person, and well-appointed. The only issue is that the light in the bathroom is on some kind of timer, which when taking a bath can leave one unexpectedly in the dark.
