Amsterdam and Rotterdam are like water and fire. Where the capital attracts hordes of tourists, young professionals and new money relying on its traditional charms; Rotterdam, completely destroyed during the 2WW, offers a spires of skyscrapers, wide NYC-like avenues and ebullient street life. Rotterdam is a brawling 'fuck off' to all things traditional and classy.
And it's the most black and funky city I've seen in Europe so far. The picks from the ZomerParade. Dig Rotterdam!
