Hilton Buenos Aires, Buenos Aires $$$$
Concierge.com's insider take:
The gleaming, futuristic Hilton Buenos Aires, designed by the esteemed Argentinean modernist Mario Roberto Álvarez, opened in 2000 in ultra-chic (and rapidly developing) Puerto Madero Este, formerly a landscape of 19th-century docks and warehouses. The Hilton played a starring role in the 2000 Argentine film Nueve Reinas (Nine Queens), and it retains a certain kind of glass-and-chrome glamour, particularly in the breathtaking seven-floor atrium lobby. Many of the 414 amenity-stuffed rooms—and the stunning rooftop pool—have sweeping views of the old docklands and the wilds of the Costanera Sur ecological reserve.
