This 1929 building was the work of Mario Palanti, the architect who also designed Palacio Barolo (Avenida de Mayo 1370). It's one of the most traditional hotels in Buenos Aires and was named after a Spanish statesman of the 19th century. In the 1930s it was the hotel chosen by the Spanish poet Federico García Lorca for his six-month stay in the city.
The hotel was also the meeting place for the literary group El Signo, which included the writers Jorge Luis Borges, Norah Lange, Oliverio Girondo, Emilio Pettoruti and Lino Spilimbergo.
