My wife and I arrived into Munich via train. We caught a tram (#18 or #19 will do) 3 stops and then walked for approx 5-10 minutes. If you are packing light this will be a breeze.
The hotel itself is very clean and the lobby/bar are kind of funky and cool. The hotel staff are very friendly and helpful as we were checking in, and continued to be as we asked questions. We stayed for two nights and had a classic room with a king size bed. The room was quite big by European standards, as well as very clean, and the bed was very comfortable.
There is free wifi in the lobby as well as two computers for you to use. Like I said, it's a little out of the way as youo have to train it to get back to Munich Central station. The area around the hotel is kind of blah as everything closes relatively early. All in all the rooms and staff were great, and if you don't mind tramming it a little bit the hotel should be a good fit.
