Torbjorn's aparrtment is just as described and we really enjoyed staying there. We were lucky to have unseasonably warm and sunny weather the first afternoon when we arrivd so we were able to enjoy the nearby Vigeland Park. The apartment is really big and we were able to relax easily...(after recovering from climbing the stairs with our suitcases!) The bus stop is close by but we actually walked both in and out of the city quite easily. Oslo is quite walkable and in nice weather it would be bikeable. This is a greta base from which to explore it.
