A very basic room with shared bath and kitchen. I only stayed one night, but the other people there seemed to be long term guests, so it felt like staying in someone else's house.
To get in you have to call the owner directly and arrange to meet, and the number was not included in my reservation. I called hotels.com to get the number. The lock on the door to my did not work, the TV did not work, and the floors were quite dirty. On the plus side, the wifi was pretty good and it's close to Oslo S.
