A gathering-point for all things interesting and beautiful in Buenos Aires, this new, discreet Recoleta boutique hotel focuses on its insider connections to provide supreme five-star concierge service, offering more of an all-encompassing travel experience than a simple hotel stay. Inside a converted mansion, there is a lot of marble and mirrors, not to mention a vast library where complimentary snacks are laid out each afternoon. The rooms are lovely—spacious suites decorated with work by local artisans, as well as antiques and leather sofas. The restaurant, Tarquino, is also excellent.
