Marriott Plaza Hotel Buenos Aires, Buenos Aires $$$$
Concierge.com's insider take:
The stately Plaza Hotel—with its elegant French facade overlooking the leafy oasis of Plaza San Martín—has been a Buenos Aires landmark ever since opening its doors in 1909. Designed by Alfred Zucker (whose best-known work is St. Patrick's Cathedral in New York), the nine-story Plaza—once upon a time the Buenos Aires Ritz—has a rich history of attracting royalty, cattle barons, and the globe-trotting polo crowd. Marriott snapped up the legendary luxury establishment in 1994 and has astutely combined modern amenities (the hotel was further renovated in 2003) with classic, white-glove sophistication, all at pretty reasonable prices. Be sure to log some time at the handsome Plaza Bar, a favorite Art-Deco haunt of B.A.'s movers and shakers.
