I've heard a lot of great things about Berlin.
"It's a very up-and-coming city, full of energy." That's what they say.
Maybe it's true. But I have to admit, I didn't feel that atmosphere when I was there. It was still an interesting place to see and perhaps you just need a local to really show you around.
There's certainly a distinct vibe to it, though. And I enjoyed seeing some of the places where they filmed parts of The Bourne Supremacy.
