Pros:
They don't get any better than this, easily the best course in Europe for maintenance, layout, variety of shots and just plain awesomeness. It's an absolute must play if you are headed into northern Sweden, the players and staff were all really friendly and welcoming to an outside player. I played the championship 9 hole course as well and it is incredibly tough and a true test of your full variety of shot making as a player. Bring your a game, you will need it on this 9 hole course. The main 18 is much shorter , but still a great test of accuracy and shape.
Cons:
The only con is that I don't live in northern Sweden.
Other Thoughts:
Do what you have to do to get there someday, it's as good a course as you will likely ever play. Pro shop, driving range, restaurant, amazingness.
