The Four Seasons Hotel Buenos Aires, which opened in 1992, is really two hotels in one. The more historic of the two is the three-story, Belle Epoque mansion, built in 1920 as a wedding gift from Félix de Álzaga Unzué, a member of a prominent local family, for his bride, Elena Peña. There are mansard ceilings and toile de Jouy wall panels, and many suites are housed here. The other building is a modern 12-floor tower, which holds the bulk of the rooms. These feature double-glass windows, private bars, and armoires with HD TVs. Every cushy amenity expected of a Four Seasons property is found in both styles.
In 2013, most of the common spaces underwent a $49 million renovation, completely overhauling the lobby and the spa, and adding two new restaurants. There’s still the Roman-style outdoor heated pool overlooking La Mansión, but to complement it, more of the outdoors has been worked into the hotel: lavishly landscaped gardens, a rooftop garden, and a glass-enclosed asado-style restaurant that can be opened up to fresh air.
