1929-39. It was a fascinating era; visually pleasing and politically mad. Also, I'd like to see the world before it was ruined by war and the post-war mass consumer culture. It wasn't necessarily a good world, but it held the promise of something far better than what came. Plus, did I mention it was visually pleasing? 
I'd choose either Stockholm or London. Or Oxford, maybe.
