We had a wonderful stay at Kari & Ingunn’s place. It’s steps away from the park that’s home to the palace, walkable to the water, and plenty of shopping and restaurants. The flat itself was very clean and spacious with a few bedrooms and sofa beds. There are two great common spaces if you want to take a rest from the sights. We got a car to drive to the Fjords, so a big plus was the parking spot. Ingunn is super responsive and helpful. Would definitely recommend this spot if you’re coming to Oslo!
