Goldenrod. I love me a good metropolis, and even though it's kinda small by Pokemon standards (even Saffron feels bigger, and that was designed the generation beforehand), it's the best place for me to live: full of hustle and bustle and activity and a big-ass shopping centre. All good things. I'd maybe have a holiday home in Blackthorn. It's probably my favourite city in terms of design (Goldenrod, as much as I love it, is kind of a mess when it comes to design particulars) and I'm sure all that alpine air and fresh Icy wind and Dragon magic and whatnot would do me good. :D
