Location: Cerrito 1455.
This luxurious building dates from 1919. It was built on behalf of the traditional Buenos Aires Alzaga Unzué Family. The facade of the palace has a very refined work of ornamentation, similar to the French castles of the Loire region, which combines bricks with stones. The building has three facades, one with a semicircular staircase and gallery that faces a courtyard of the Park Hyatt Hotel. In its current role as an extension of the hotel, the mansion is where luxury suites and several special reception halls are located.
