Warsaw, Poland is more than just a historic city. Second World War was harsh to them and the communist regime that came afterward is not an easy one to handle. Although scattered from the foundation, now Warsaw is a vivid and modern city. For a good background, check this documentary website. However, if you’re in Warsaw during summer time, go out of the Old Town and experience the usual city life. Polish people have a thing for deckchairs, ice-cream and beer, so my personal recommendation is to lie down and enjoy the life.
