We stayed in John and Hilde's flat one night and it was absolutely amazing. The flat was very spacious and beautiful and John was really really nice(Unfortunately we couldn't see Hilde as she was away for her holidays). Bed was comfortable, hot water ran really well, kitchen was very well equipped so our overall staying was very satisfying. Especially, as we stayed in Oslo just for one day the schedule was pretty tight and John gave us very detail and useful tips for sightseeing in Oslo which we appreciated a lot. He even gave us restaurant recommendation which we loved so much and my Norwegian friend was quite impressed that we visited that restaurant! :) If I have any chance to go back to Oslo I will def stay in his place again and I do recommend this place for your staying in Oslo!
