på Sveriges framsida = In the front of Sweden/ Swedish front(side).
This may sound weird, but it's like a mock war between the east coast and the west coast in Sweden. Both claim to be the front of Sweden, faceing the world while the other would be in the back.
I think in the very beginning it was Göteborg (the city) who claimed that name "Sveriges framsida" or more playful "Bästsidan" (The best side) But later, just as Lena told, it has become a feud between the west-coast & east-coast.
"Maria, you are very welcome TO our home... we look forward to see you here on the front side of Sweden"
