Stayed 2 nights, beginning and end of a two week trip. First night was second floor and there's no elevator. The room was at the rear and if you like to sleep with the window open, you better like trains screaming by all night. The ceiling was vaulted and angled and intruded on the wall side of the bed.
The second night there we asked for and got a ground floor room. Much more roomy, and because it was in front, you couldn't hear the trains.
I would stay here again if visiting Munich. We normally stay in Trudering. So if you like to be out of the City a bit, but close to the S Bahn to get there, this is a prime location.
