I'm renting out my extraroom in a very cozy apartment in the heart of Oslo for short periods of time. The place is near everything: the City center, Barcode, The Opera, Munch museum, Botanical garden, Outside bath, boats to the islands and lots of cozy restaurants, bars and cafes. Its also close to the railway station and to public transport. A really nice place to stay for a few days.
The apartment lies on the 5. floor in a tall building and there is an amazing wiew from both sides.
