Very beautiful lacality, some parks at a walking distance. You can use buses, T-bane (Majorstuen) or, if you like walking, go to Royal Palace and quay on foot. In the appartment you can find everything you need and the shop round the corner works till 11 p.m.
Espen and his family are very friendly and hospitale.Thank you for your advice about the ferry. I used it for my cruise among islands in Oslo-fjord.
I love Oslo and my living in the appartment made it à la at home.
