Trollvasbu is a very cozy DNT hiker's cabin. You need a DNT hut key to use the hut. There are 16 beds here. There is even electricity available via solar panels, but only 12V as electric light. In winter, of course, there is little of that. There is gas for cooking and a wood-burning stove for heating. You get water from the river next door. 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.
