[citation needed] Among the events held at the hotel throughout its history, in 1966/67 the couturier Nina Ricci presented her Autumn-Winter haute couture collection in its salons, where singers such as Julio Iglesias have also performed, Antonio Machín, Raphael, Joan Manuel Serrat, Rita Pavone or Massiel, among others.

[citation needed] The hotel was built by the architects Manuel Muñoz Monasterio and Juan Jáuregui Briales in 1959–1960, who incorporated in its design the revisionist tendencies of the modern movement in those years, with the introduction of sets of colors, textures, wavy lines, etc..

The two grand staircases in the lobby set the appearance of the main facade, characterized by a semi-cylindrical body.

Completely renovated, it offers different types of accommodation with a modern décor that reflects the hotel's heritage from the 1950s.
