We stayed here to visit Therme Erding nearby. It was the cheapest of decent enough quality in the area, and was just right to serve our purpose. Clean, simple, comfortable, quiet hotel. Breakfast was free, and it was a nice change to have some vegetarian 'meats' on offer, as well as a boil your own egg section.
We would happily stay here again. Just be aware that to and from the spa, Google maps tries to take you down a path that is taken up by a private industrial unit. Go via the Best Western instead, through the residential street.
