4. Prague, Czech Republic
This city appears straight out of a fairy tale. It possesses countless bridges – connecting the old city center with the newer section. The party scene at night is amongst the best you’ll find on the continent. Beer is also cheaper than water – something many tourists take advantage of. People are also exceptionally nice here, and many speak English fluently. While Prague has become a trendy vacation spot for families in recent years, it’s still a destination for those 20-somethings in need of a good time.
