First opened in 1932, this was the first European style luxury hotel to land in Argentina and it was named as a Historical Monument in 2003. Evocative of its heydey, a stay here will take you back in time, to an era of swanky grandiose elegance, replete with chandeliers, antiques, gilt-framed oil paintings and cut crystal. Those preferring a modern vibe should request a room on the top floor, which received a refurb in 2016. Also on the top floor is a new spa, pool area and funky rooftop bar with amazing city vistas. Dinner is served all the way down in the basement, where a French menu by Relais & Châteaux chef Jean-Paul Bondoux is presented – and tea in the atrium is a charming way to spend a post-sightseeing afternoon.
