I stayed in Torgeir's house for 3 nights with my husband, daughter, her husband and two grandchildren, and my son and his fiancee. There was plenty of room for all of us. This is a large house with a beautiful garden in the middle of Oslo near parks, cafes, grocery store, and local transportation. It is on a short side road so no street traffic noise.
It has a spacious kitchen, well equipped, and two living room/den areas, so lots of space. There is a separate apartment below but we didn't hear the other renters in our apartment but enjoyed meeting them in the garden. The garden has a swing couch and large table and benches so eating outside is lovely. Torgeir was very responsive to my texts even when he was traveling in other parts of Europe. We had a fabulous stay in this house.
