A nice room in a shared flat where other travellers might stay. The flat has everything essential for cooking and a good rest. The location is central and 5-10 min walk from the train station Oslo S. Quiet neighbourhood.
I spent a few days here in winter. The heaters work perfect, just need to be turned on. Also, use the hood when cooking, otherwise the heating plate might turn off for a while.
Lina provides clear instructions and gives ideas about places for a visit, and she is quite responsive in Airbnb chat.
Overall, I definitely recommend this place, you'll find here everything needed and can reach places in the town pretty easily.
