We stayed for two nights at Terje's place and it was one of the best air bnb rooms we have stayed at It was as good as a hotel room !
Terje is a great guy, very kind, friendly and helpful. Checkin was really smooth with his inctructions. His appartment is beautiful and cozy and very centrally located( 10 mins walk to the central station and 5 mins walk to the tram or bus stop). He provides day pass to the guests which makes commuting even more convenient and easy.
We were greeted with chocolates and candies in the room and there is coffee and tea as well. I highly highly recommend his place and we would definitely stay at his if we come back to Oslo.
