Katherine's place is super close to public transportation and in a nice, central spot in Oslo. It's located to everything that you could possibly need and she's super helpful. I was able to talk with her and she was super warm and hospitable, asking if there was anything that I needed. Her space was small, but neat and not super cramped. It might be a stretch for two people, but for a solo traveler, this place has everything that you could ever need.
