Puerto Madero, Buenos Aires
Concierge.com's insider take:
It's still shocking to many porteños that Puerto Madero—once a run-down dock area—has now surpassed Recoleta as B.A.'s highest-rent district. It's a barrio that didn't even officially exist until 1994, when massive renewal transformed a jumble of derelict brick warehouses and deserted streets into the TriBeCa of South America. These days, the four diques (locks) that define the old port are home to Cabaña Las Lilas, the best steakhouse in Argentina; Santiago Calatrava's lyrelike suspension bridge, Puente de la Mujer; and Faena Hotel + Universe, the mind-bogglingly over-the-top hotel that design superstar Philippe Starck carved out of a 1902 industrial grain warehouse.
