Stayed in the Radisson Blu for one night earlier this week.. Arriving late, despite not having status I was upgraded from the booked superior room to a suite. This was a large sitting room with a large bedroom behind a movable curtain.
With an outside temperature of -10°C I was glad to have a very short exposed walk from the terminal to the covered walkway to reception.
The choice at breakfast was excellent. especially the herrings and salmon.
After checkout the next morning I left my bag at the hotel, took a train into Oslo, and returned later to collect the bag for my flight.
A very convenient airport hotel.
