This is one of the best hotels in Oslo.
Not cheap, but very good standard.
Frontdesk was plenty both during checkin and checkout, and very warm and friendly.
One of the best breakfasts i have ever seen in Norway and unlike other hotels in the same class there were actually free tables here as well. A big plus.
Location is as central as it gets, more or less directly connected to the central station.
My only complain was the temperature in the room. It was boiling hot, and all my colleagues complaining about the same thing. Not possible to get it colder, because the knob for regulating it on the switch was gone.
All in all highly recommended both for business and pleasure.More
