If you don’t understand Swedish, enjoy their photos.
According to Biletto – when posting this – there are still spots available in shared accommodation. It is mass-lodging in one large room so you meed to bring your own sleeping stuff: mattress & sleeping bag. There are 3 showers, loads of toilets and refridgerators.
Remember the golden rule – Leave no trace! The lodging shall be as clean when you leave as it was when you arrived.
