Finland, of course!
Curious to see so many mentions of Sweden and Norway, but almost no interest in Finland.
That's because you Finnish are
different
J/K, I love Finland, only country in the world when you can canoe for miles in (relative) wilderness and stumble upon a public sauna to use after a hard day of rowing. Absolutely winning country. But the whole of Scandinavia, I couldn't deal with your winters. I'll stick to visiting in the summers.
I've stayed in Switzerland for a while and it's bonkers if you enjoy nature, but we had a hard time really connecting with the Swiss. Could be us, but I think Swiss people can be hard to really get to know.
If there's one country I'd love to live for a while, it's
Italy. Winning combination of nature, climate, culture, food, variety.. I just don't speak the language that well. But really, Italy is something different (for me).
I also wouldn't mind hanging out in Oregon for a while.
