We stayed for 3 nights in a private tent. Of course it was a bit loud, but that's to expect when you sleep in tents. The staff was really nice and open to answer any questions. The community bar was nicely set up. They had any kind of drinks and a selection of food (it wasn't that nice, but you could also get food from the supermarket and eat it there).
I would definitely recommend this unusual hostel.
It was one of kopenhagens "problem quarters" although we still felt safe enough. With the metro it was only 17 minutes to the city centre, but you could also go by bike, which was really cool.
