The CSA Nordic Summit and Summer Conference takes place at Vulcan Arena, in the center of Oslo. A popular concert venue, the Vulcan Arena features several rooms and stages in a modern building with interesting architectural features.
The conference hotel is next-door, with direct walk-in from the hotel to the conference venue.
Across the street from the hotel and conference venue is Mathallen, a food market with both local Norwegian food, great beers and international eating options!
You can book your room directly, and use the CSA Nordic Summit to receive a discount.
