Mona and her daughter were great hosts. I only had the chance to speak with them for a few minutes, but they were both very informative and communicative about the things to do in Oslo and arranging plans. Mona was nice enough to let me keep my duffel there on my check out date since I had a late flight, which was greatly appreciated.
Great location, about 12 min ride into town, 15 into the Norway museum area.
