CPH/ARN Lounges
The CPH lounges are larger and on two levels. They have the traditional SAS blond wood furniture and colorful fabric covered chairs. They have some computers set up for browsing the internet and food and drinks. The last time I was at the CPH lounge, I thought it was looking a tad tired. The lounge complex is centrally located in the main terminal and just beyond passport control. You can't miss them.
At ARN, the international lounge is on the second floor and a bit removed from the rest of the terminal. It's comfortable and like most, has blond wood furniture, computers, drinks etc. They're all pretty much the same. As for me, I prefer the SAS Lounge at Heathrow Terminal 3. It's a joint operated lounge with Air Canada and has lots of periodicals, newspapers, etc.
