The tony Parisian flat of Lee Radziwill, the sister of former First Lady Jackie Kennedy Onassis, is being sold by the 84-year-old decorator for $4 million, or $3.4 million euros.

The flat has four bedrooms, two reception areas and a cellar in the much coveted eighth arrondissement, according to the New York Post. Lee Radziwill, a socialite and the younger sister of Jackie, decorated the 1,615 square feet pied-a-terre that is housed in an 1890s Hausmann-era building, according to an article by Moneyish.

The flat is located on the sixth floor and its 130-square foot balcony gives potential swanky owners the opportunity to sip Champagne while viewing the Eiffel Tower.

Nowadays, Radziwill alternates between living either in Paris at the Hotel Plaza Athenee or in New York, Page Six said. Her sister was beloved by the French and had traveled to the country before her marriage to John F. Kennedy.
