My wife and I stayed there laste year for New Year's. Very nice hotel thatough as others have said, not as nice as the Hilton Munich Park. Service was excellent. Rooms were nicer than any Hilton I have stayed in in the states.

Best part though is the subway station below the hotel. S8 train takes you from the airport directly to the hotel (25-35 minutes I think). Also, within a few train stops of all the sights in the city. Quick walk to museums, theater, concerts, etc.
