I had a very enjoyable stay at Arne's apartment! It was spacious, immaculately clean, and very comfortable. There was a well-equipped kitcken and a nice eating area with a lovely view. Arne was very friendly and offered helpful information about public transportation. The metro is a 10-15 minute walk, making it very convenient to get to the city center. I'd be glad to stay there again on a future trip to Oslo!
