Buenos Aires City

Buenos Aires needs 3 days: the historic center (Plaza de Mayo, Casa Rosada) on one, La Boca and San Telmo on another, and Palermo (with its nightlife and food scene) on the third. September-November brings the southern hemisphere spring, with mild temperatures ahead of the humid porteño summer heat. It's one of South America's cheapest capitals for foreign tourists, with an exchange rate that favors the dollar and euro. It's known as the «Paris of South America» for its European architecture, and tango, born in its outskirts in the late 19th century, remains its most recognized cultural signature worldwide.
