Ann-Kristin's apartment is very nicely appointed with everything one would need for a comfortable stay, with thoughtful touches and supplied with many amenities. The apartment was larger than I expected and perfect for our stay. Her son, Sigurd, checked us in with a tour of the apartment and gave us several restaurant recommendations, which were helpful. The apartment is centrally located in the historic core of Oslo, a short walk from the airport express train and to the ferry dock for the ferry to the viking museum.
