If you're looking to go to Neuschwanstein castle, expect to dedicate the entire day as it is 1.5 hours by bus or 45 minutes by car. If taking the bus, be aware of departure times, because Oberammergau is not a highly traveled city (for example at time of writing, the last bus for Oberammergau left at 6pm). This was too early considering the how busy Neuschwanstein/Schwangau was.
The hotel itself is very nice; has a very of the alps, the people are friendly, staff is kind and 'real.' When looking for the hotel, "Hotel Garni" is more clearly noted than anything else.
Overall, the hotel is wonderful if visiting this region - a nice bavarian town with a homey yet touristy feel.
