Nonsbu is a small, rustic DNT hiker's hut. You need a DNT hut key to use the hut. There are only 6 beds here. Reservations can be made via the DNT or Ut.no apps. There is no electricity here. There is gas for cooking and a wood-burning stove for heating. There is firewood in the toilet block, where there is also a squat toilet with a styrofoam seat - it's warmer than expected. The use of the hut costs money and can be paid for in various ways by app, with Vipps or afterwards at the DNT in Tromsö.
