By arriving early, we afforded ourselves the opportunity to learn more about Buenos Aires. To do so, we hired a guide for the day and walked the city's old section and some of the newer areas. The city is full of amazing architecture and history. It is sometimes referred to as the "Paris of South America" as many of its streets are reminiscent of the European city with architecture and trees. The tango show was extremely entertaining with high energy, yet sensual dancing.
