The private apartments of the residence comprise three rooms set slightly apart from the reception rooms on the ground floor. In her bedroom, Nélie Jacquemart chose to return to the atmosphere of the reign of Louis XV. She installed old wood panelling around a large daybed and positioned some of her most beautiful furniture here, along with a multitude of the small tables with which she liked to surround herself. Silks from Lyon hang on the walls along with two pastel paintings, including the exceptional Portrait of a man by Maurice Quentin de la Tour.
She had a small conservatory sitting room built on the terrace, which she made into her office.
