Stayed 3 nights at the apartment of John and Tom. Unfortunately they went on a short trip, so I didn't get to know them really. But at my arrival I met them and they were superfriendly and so sympathic. They would help me with questions and tips where to go, etc. The apartment was the best choice too, in the heart of oslo and it felt like home away from home. And of course I loved Hope the housecat:-) If you want to have a comfortable stay in the city center (it was quiet at night btw) I can really recommend this apartment!
