I'd want to live in Zora's Domain. I'll never forget playing Zelda's Lullaby to part the waterfall for the first time.
Otherwise, maybe one of the islands from Wind Waker. Like the private oasis. Or possibly Skyloft. I didn't love Skyloft at first - I didn't think it had as much character as say Clock Town (I recently replayed Majora's Mask) but it's really grown on me.
