Sonja is super nice and forthcoming. All messages were replied quickly and no question left unanswered. The apartment is cozy and really well equipped (you even got a tv with chrome cast and it is way bigger than it looks on the photos ). It is located in a calm location wherefrom one can perfectly explore the city and all the highlights in Oslo by bus/tram/bicycle. Our stay at Sonja’s place was just perfect :) thank you!
