Martin whom I met in person was a great host, helpful and with a very nice sense of humor. The room was very clean as well as the bathroom which has a very nice touch with the surrounding jazz music in it. If you are searching for a room inside a host house in a central area, then you should look no further. Very close to tram, subway and airport busses, you can explore Oslo easily and relaxed. For some exploration tips, Martin would be there to guide you. Highly recommended
