Berlin offers a wonderful combination of history, architecture and culture and an amazing number of sights, although it is not as centralized or small as other European cities. Sometimes the best things about it have nothing to do with landmarks: simply strolling along one of hundreds of charming streets complete with cafés is pleasurable enough.
Berlin is also perhaps one of the greenest cities in Europe: over 60% of its surface area is either a park or a river… it even has more bridges than Venice!
There is no city in Europe that parties harder than Berlin. The nightlife of most cities is tame (in some instances lame) in comparison to this city. There are lots of great clubs and dance parlors, just ask around for the best places. The Berliners are often friendly and extremely helpful, although you may also encounter the famous “Berliner Schnauze,” a certain brusqueness that can seem rude.
