Great experience! Olaf was easy to communicate with and very friendly. He did a a lot of make sure we had a comfortable stay. His apartment was great, and located in a nice area. Everything was as advertised, and everything seemed very new. It's conveniently located close to a supermarket, and only a short bus ride from the city centre. I would definitely recommend Olaf as a host, and I would love to stay here again if I visit Oslo!
