I stayed in one of the single rooms, no private bathroom. The bed was very comfortable, the space was very comfortable to use as I explored the south of Iceland and it is close to many wonderful sights, and near enough to Vik for amenities.
The breakfast option was an additional cost, and too expensive to be worthwhile for me. It is a no frills experience, very simple and straightforward. Check in is at 4 PM and no staff is present until then, making it a bit stressful if you arrive and don't know that.
