This hotel is terrifically situated near Munich's premier site and many key transit options. This makes getting around the city a breeze. The hotel also has unique amenities and a treat room for guests. However, if your room is on the south side of the building, you can expect near constant noise from the city trams until about 1am. On the weekends, you can add the party-like atmosphere from the street below stretching deep into the night as well.
If you don't plan to spend much time in your room, this won't be a big issue (until bed time). Since having the trams close is a major benefit for hotel experience, I'm not going to dock the hotel too much. The staff are good, the amenities good, the hotel is clean, etc...Just be aware if you're a light sleeper you should try to get a room on the other side.
