La Boca, Buenos Aires
Concierge.com's insider take:
The salty old harbor of La Boca—with its working-class swagger, old-school cantinas, and copious graffiti—is thought to be the barrio where 19th-century Genovese immigrants first danced the tango. Modern-day practitioners can be seen strutting their stuff along the rainbow-hued alleyway known as Caminito, La Boca's open-air museum, art gallery, and souvenir market (see above). It's a total tourist trap, but an irresistible one that even the locals profess a grudging affection for. La Boca is also the stomping ground of Boca Juniors, the beloved soccer powerhouse whose stadium, La Bombonera (805 Brandsen), makes up the center—spiritual as well as geographic—of the neighborhood.
