I love cooler weather and more isolate places primarily, but really preferences hardly exist for me and I prefer variation.
My dream home at the moment would be in Switzerland: Eco friendly, cool, neutral, not a big crowded type place, and one of the highest life expectancies in the world. My first thought was France, in the North it's cool as well, and I love French culture, but I figured that Switzerland I can still be in French culture and a trip to France would probably be a lot easier from Switzerland. I can also see German and Italian stuff as well. Then being in Europe I could go to a lot of other places. Also as a linguaphile a tri-lingual place sounds cool to me
I'm also very interested in Asia, particularly Japan since that's would have been the best place as far as I could have seen (Using the past tense because it's not so great right now, but Japan is very modernized and such whereas the rest of Asia is either in a war, impoverished, or under horrible government control.) Also Japanese culture is awesome.
I guess somewhere real isolate and cold like Siberia or North Canada would be cool but that's a little extreme in my opinion.
