This landmark hotel ups the ante for elegance in Buenos Aires—its two buildings, a restored 1930s-era mansion and a 17-story tower, are connected by an underground art gallery and an expansive, leafy garden that's among the city's most attractive outdoor area. The rooms are decorated in rich wood, elegant marble, and soft-to-the-touch Argentine leather. Sip a whiskey at the Oak Bar, constructed from 17th-century carvings from a Normandy castle, or on the patio overlooking
the garden. Be sure to visit the Ahin Spa (named after a Mapuche Indian welcoming ritual), which has five suites offering holistic and beauty treatments. The 3,500-bottle Wine Library is a unique attraction.
