I spent a weekend here (Friday night - Sunday morning) at a conferance. I've got two beds for myself, and the room elsewise was great for the purpose. Conference hall was big, nice chairs, a good AV system. The lobby had FREE (!) soft ice and popcorn as well as cake and all your desires in coffie, hot chocolate and tee. Breakfast great and big, lunch quite the same as breakfast. The dinners were not so good, we got typical "nice resturant" plates, but it wern't awful either.
Cons:
- The bus from the airport to the hotel: 70 NOK!
- Trian from airport to Oslo Centre: about 80 at it's cheapest = 300 NOK just to get from and to town.
- The mini bar was expencive (but there were a gas station nearby)
- TV alarm didn't work.
