My mom lives in the city and my dad lives in the countryside (or well, now it's getting more popular to move there so it's perhaps not "countryside" anymore, but it's outside of the city at least).
I like staying at my dad's place during summer since you can sit in the garden, take walks and really experiencing nature. But for all of the other seasons I'm more of a city girl. I like living close to the shopping, university, transportation etc. It's easier and I can visit my friends more often.
So, to sum up I would say that I prefer the city. But I really do love the countryside as well!
Anywhere just your favourite, perhaps that is your choose.
I prefer to live in relatively smaller towns rather than metros.
