That's a toughie. Is there a specific time we live there? As in right now? Right now I would love to be in Daegu, South Korea. But if we were given eras to live in I would probably choose....... Hawaii before the US claimed it. Or Native American glory years, probably with the Cherokee.
Technically you're living in a place temporarily while you're visiting it.
Anyways, I like where I am now, but if I would be able to visit someplace I think it would be Germany, mostly because a good amount of my ancestors came from there.
