This room is a great base to spending a few days in Oslo. It is small, but makes excellent use of the space so that you have everything for your stay. Heating, shower, stove : everything works well, and the bed is comfortable. Location is also perfect: very central, beside a sweet old bakery and a beautiful cemetery. And it's a great value for the price!
Some notes for future guests: there is no elevator, and no place to hang anything (clothes, jacket, etc). The heating has an on/off switch on the side of the radiator (took me a few minutes to figure out how to operate it).
I particularly commend the flexibility of my hosts, as they allowed me to check in early and leave some luggage behind on the last day as I explored the city. Thank you!
