A sprawling megacity with a metro population of more than 21 million,São PauloisBrazil’s business and financial capital. For leisure travelers, however, its airport is often the point of arrival in South America, as well as a convenient hub around which to construct an itinerary. On our recent trip, we decided to take a couple of days to recuperate after the 10-hour overnight flight from New York. On previous such occasions, we have stayed at theHotel Fasano São Paulo, a 60-room property in the center of the city, a short walk from the main thoroughfare, Avenida Paulista.
