A clean and comfortable apartment in a great area, however it is poorly equipped, impractical & noisy (1st floor right next to the road+tram line).
It’s great if you’re looking for somewhere to drop your bags and lay your head while you explore Oslo, but not suitable for a longer stay &/or someone who will working in the apartment.
Owner’s apartment is also right next door, and linked to this apartment with an door which you can’t lock yourself from the inside.
