Depending on your level of comfort with "roughing it" THE TENT is either heaven or hell. For me, it was a good experience.
The tent is BY FAR the least expensive hostel in the city, and equally unique. For backpackers with their own tent, there is a small yard which was populated by 50 or so other tents at the time of my visit. Essentially, you are stacked up with a few feet between yourself and your neighbors.
Also offered is space in the large communal tent, which is filled with squeaky bunks, and equally squeaky lockers. (bring your own lock.) There are somewhat clean (by american standards) showers and restrooms, bike rentals, wifi, good cheap food, a fire pit with communal seating, and a very friendly staff.
If you are used to roughing it, love to meet people, or just can't bear to be far from Nymphenburg Palace than this is a spot you should check out. Follow the signs from the street car to the end of Franz Schrank Strasse, then go left up the path.
