If you're going to the Allianz Arena, this is a great location. If you want to spend a lot of time in the city itself, you may want a closer placement.
The local is okay for general purposes. The area is super-safe, but also sterile due to its being remote. There is a large grocery nearby, and that helps you obtain goodies for any adventures, but other than that, think "strip-mall" culture.
For the Allianz, we caught the train quite easily to both the arena and downtown. Walking home from the Allianz is close enough (it's 2.4 miles), but you do need to stay WEST of the tracks. If you're east, there is a path, but it does take a little bit of courage as you have to go under a shortish bridge to get back to the other path.
Other than that, the place is quite modern with furniture that is uncomfortable, but not the beds. They are okay with seemingly common heavy comforters that all modern European hotels share. The showers have clear glass, and the showerhead has a waterfall placement that inspired my wife and me.
Overall, this was our best hotel experience on a recent trip and I recommend it to others.
