The rooms were clean and basic. There are digital kiosks for checking in, but we were helped by the reception desk.
The hotel has easy access to Munich via a bus that runs to the S8 Hallbergmoos train station every 20 minutes or so.
Not as convenient as being within walking distance to the train station, but not bad.
The shuttle to the airport was not free, but was not expensive, 7€ per adult.
