In my little "Witch House" in Weilheim near Munich I rent a cute room for girls only. We have to share my bathroom and kitchen so we have to come along. Another option is a shower in the outhouse next entrance.
You can reach down town Munich in about 30 mins by train.
The alps and the Neuschwanstein Castle are very close as well as some wonderful lakes.
Free highspeed WIFI!
Additional mattress for 15,- Euro.
