Here's what Lonely Planet said about Philly: "Visited by Pope Francis, hosting the Democratic National Convention in July, and freshly crowned as the US's first and only World Heritage City (joining the ranks of Cairo, Paris and Jerusalem), Philly's on a roll. NYC's more neighborly neighbor is experiencing a transformation to its urban core, as many U.S. cities are right now. Craft breweries? Check. Hot new locavore restaurants? Big check. But Philadelphia is steadfastly managing to retain its historic roots and gritty flavor, as well as its affordability - a pleasant surprise for a city so cosmopolitan and accessible. Hands up to the sky, Rocky fans: celebrate the film's 40th anniversary in 2016 with a sprint up the 72 steps of the Philadelphia Museum of Art."
