This is a self-service cabin, which means that that you do everything by yourself. The cabin is not accessible by motorized vehicles - you will have to reach it by foot (about 9 km). It is mostly used for trekkers. Upon arrival, you register yourself in a log book. Later, you'll revive a bill for your stay. The cabin have a storage with food you can take from, but you will have to register what you take and pay for it later. From mid- to late summer and around easter, there is a small chance for the cabin being full, but this was not the case when I was there in late July a couple of years ago, when I went for a longer hike between cabins like this one in the surrounding mountains.
