We enjoyed our stay at Sigvart's place so much! The apartment is spotless and well-designed. The bedroom is really small, but ship-like - lots of storage, really comfortable bed and bedding. Sofa bed is queen-sized, comfortable for our grown daughter and easy to pull out and put back. The location can't be beat. Right on the bus line, and walkable to nearly everywhere else in the city. We walked to the harbor, the museums, the opera house, dinner . . .
We had a hiccup when we got there with the key handoff, but we called the host and it was taken care of really quickly.
The place is on top of a complex that has a supermarket, an Italian market, a food hall, wine shop, and several restaurants, including one that has a MIchelin star!
Would definitely recommend this place, and stay there again if we return to Oslo.
