[1] The hotel was commissioned by the Costes brothers, Jean-Louis and Gilbert,[1] from the designer and interior architect Jacques Garcia[1] in 1991.

The hotel is now renowned as a den of opulence and was built in conjunction with Klay Robson as Developer and construction consultant (the design maxim was "all things in excess").

The Costes Apple Music Channel [5] features a monthly 15-song compilation featuring premieres and some exclusive unreleased songs curated in an eclectic and contemporary approach, ranging from electronica to 60s French chanson.

In 2014, Jean-Louis Costes bought the adjacent Hotel Lotti, opened in 1910.

He gutted it and turned it into a new wing of the hotel, which opened in 2020, giving it a new main entrance on Rue de Castiglione.
