5/5 for Mats and little Stella (Dog). I had a very personal and welcoming experience staying with them for 3 nights. The room and the whole apartment is newly renovated, about 15 minute by tram from the city center and close to Majorstuen neighbourhood (place to be). I can recommend this place to every solo travel visiting Oslo. Mats is a super kind host, he even prepared nice coffee in the mornings.
Mange takk!
