I had a great time staying at Kim and Jen's. The room was spacious (I think bigger than my whole apartment in East Village), bright and very clean. Jen gave me some good advice on how to explore Oslo as soon as I checked in, which helped a lot, since I didn't have much time in Oslo. They are both so friendly and warm and helpful. The location is also very nice, everything you need is around the corner, and the harbor and the castle was an easy 20 minute walk away. Highly recommend this place!
