I was in Stockholm last summer and flew over to play two rounds, 18 one day and 27 the next day. There are a limited number of sea coast holes, with remaining holes through pine forest, meadow, or mounding and dunes giving it a Scottsh feel. Two holes on the back nine have the look and feel of coastal lowlands in South Carolina. The nine hole course is worth a play.
It's a nice members club with aestheticaly attractive and functional structures. I played with members who werre knowledgeable about the development of the course and club.
I think the Swedish rankings as the #1 course have to do with the natural look and feel, as contrasted with the Stadium Course at Bro Hof Slott, which is a clone of the Stadium Course at Sawgrass.
I'm part Swedish and hadn't visited Stockholm. I liked my time in Stockholm. The golf I played was a partial diversion.
