We stayed three nights at John's place and I really wish we could have stayed longer. John and Tom are very nice and welcoming persons. John answered very promptly to our last minute request and made himself available to welcome us when we arrived quite late in the evening. His neighborhood is perfectly placed in the center of Oslo and close to every thing.
The apartment, itself is great. The room is small but warm and comfortable. Everything is perfectly clean. Allergic ones be careful of Hope, the house lovely cat.
I will definitely return to John's for my next visit to Oslo !
