Over the years this landmark has hosted some of the country's biggest movers and shakers, including Juan and Eva Perón—no surprise, since it has a presidential suite that occupies an entire floor. Built in 1928, the Spanish baroque structure has some of the most luxurious rooms in the NH chain. Rooms have big, bouncy beds and handsome wood desks; the small bathrooms disappoint, though. Suites have private terraces overlooking the city and the Río de la Plata. The lobby
café sits a half story above the sidewalk and offers grand views of passersby.
