Our experience in Oslo

Accommodation - Air BnB.
Probably the most modern of all our accommodations. The location was superb, close to a major tram stop and an easy walk to the heart of the city as well as the train station. Host very accommodating. Although located fronting a major street it was surprisingly quiet. Kitchen and bathroom were both fine, everything worked as it should. W/D combo worked fine. 

Transportation.
Superb system of trams (light rail). Used the Oslo Pass to get around and everything went off without a hitch.

Attraction.
Ekeberg Park and the outdoor sculptures, Fram Museum, the Kon Tiki Museum, the Munch Museum, a harbor cruise, Vigeland Sculpture installations in Frogner Park, the Norsk Folk Museum.
