I really recommend to stay at Ninas place. She is very kind and a very good host!
You will reach every sightseeing point very easily with bike (bike sharing next to the airbnb), tram or like we did it most of the time by walking.
The room is very quite and has a bed wich fits to people.
We really had no complains and we are happy that we choosed Ninas place for our visit in Oslo.
Great city
Great flat
Great host!
