Woow, I really thought you had been to Berlin. xD
I don't think I've been there either.
I've been to Amsterdam, Brussels, Paris and London though. (I'm actually going to London again in May. (': )
And I realllyyy want to go to Rome someday ;w; I think I'd really like Italy even though I've never been there before.
But then again, I want to go to many places.
