The hotel in itself was an amazing experience, as it was a very historical place with low ceilings and loads of atmosphere. At our checkin the service was not very friendly. My wife made the checkin while I parked the car, and she do not speak very much German, and when she tried to communicate with the clerk in english he seemed almost offended.
However the next day, the service was a lot nicer (from a different clerk) and overall it was a nice stay.
