Well goin by the places I have actually been to, so far in my life, it would be either Canada or Stockholm.
Loved Quebec and the pace just seemed sooooo relaxed and Stockholm is just stunning. Isn't it strange how both places I like have very small populations? Coincedence? No, I don't think so! The people in Stockholm were so friendly, not so much in Quebec! They really don't like it when you speak English!!! But still, beautiful city and just so clean.
