The room was very comfortable for 4 persons. It is located in a flat with multiple other rooms. You share the bath rooms and the kitchen. It is very clean (daily cleaning crew) and you don't hear that much from the other guests. The location is very central, with a supermarket just 1min walking distance. Also a recommended burger restaurant 1min away.
For us the price (in comparison to other AirBnB in Oslo), the perfected location and the clean & comfortable room is worth a good recommendation.
Hope to come again to visit the great city and have a comfortable stay.
