First the good stuff - the location is excellent, close to the Aker Brygge waterfront, the most attractive part of Oslo. Despite being in the middle of a tourist area it is also quiet. The host was very helpful once we arrived, the bed was clean and comfortable, the bathroom was clean and well equipped.
BUT - the room is very small. For one night it was just what we needed, but we would not have wanted to stay for longer. My wife and I are not tall (160cms), but we could not easily both stand up in the room at the same time. There is nowhere to put suitcases and the storage space is minimal.
