If I were contemplating on where to stay in Oslo, I would definitely pick Ivar's place. Not only is the accommodation amazing itself with ammenities in perfect condition, cleanliness, comfortable beds and a huge bathroom to cater to your needs, but the hosts themselves are definitely one of the most hospitable and welcoming people I ever met (and I've been traveling quite a lot for the past couple of years). This place feels like home away from home rather than just your typical airbnb in a foreign city to spend the night at.
