Lovely apartment. Very clean and tidy, and nicely furnished. Has everything you need for a stay in Oslo. The location is just outside the city center, in what is probably the coolest neighborhood in Oslo - Grünerløkka. You can hang around there, or take the tram for 10 minutes to the city center. Either way, this apartment is a wonderful base for your journey.
Didn't meet the owner, just picked up the keys from a local grocery store.
