Location, location, location -- and price. Gung and Martin are very easy to find near the train and bus station, with almost the whole walk inside the terminals to protect from rain. They are very friendly and helpful. The room was clean and spacious. Don't be worried by some graffiti as you walk through the courtyard to their door; it's in a working-class neighborhood but safe and nice inside. You are sharing the bathroom with three other rooms with multiple beds, but there is a toilet-only bathroom in the stairwell for emergencies. Simple accommdations but a real bargain, and I learned a great deal about Norway in a fascinating conversation with Martin.
