The one is my fave nordic countries is Sweden. Like for many people for me Stockholm is associated with roofs where Carlson lives, and also with the characters and events of the book of Stieg Larsson "The Girl with the Dragon Tattoo" as well as a film made based on this novel. But the main thing I always remember is old ancestors of the swedes: the vikings. I deeply respect their heritage, and not just because of films about the Thor, I like norse mythology a long time. Like Norway, Sweden is in my list of my fave countries. And not its cities and attractions, but more the wild nature.
You must visit Sweden and see its nature! Take care of you! Big kisses for you! Meaow=*
