From a Curbed.com online article:
Part of the luxury hotel chain Les Airelles, Le Grand Contrôle is named for the building it will occupy—a 17th-century structure once used as the finance hub of the palace. The hotel will have 14 rooms, some of them apartments, as well as a wellness center, indoor swimming pool, and an Alain Ducase restaurant.
Its views include the ornate gardens outside of the Orangery, a building custom built for housing the palace’s array of tropical trees during winter.
Though the hotel is keeping mum about the details on the interior, The Spaces reports that Parisian designer Christophe Tollemer will render the hotel in classic 18th-century style, gold, glass, and molding. There’s no word on rates yet, but we’ll go ahead and guess they’ll be as haute as the hotel itself.
