740 Park Avenue #6/7A Upper East Side, New York NY 10021

LLNYC's look at listings:

At 740 Park Avenue, Manhattan's most prestigious co-op building, a $29.5 million listing has just gone on sale.

This isn't the first time that the tony 12-room duplex has been up for grabs; it was originally listed for $44 million in 2014, and has since undergone numerous discounts.

The current owner is finance guy David Ganek and his wife Danielle. It's the home's previous owners though, that are the really interesting ones; John V. Bouvier III and his wife, Janet — otherwise known as the parents of Jacqueline Kennedy Onassis - lived in the palatial apartment for six years in the 1930s, which explains why it’s known as the Bouvier apartment. And Jackie O's grandfather, James Lee, was the developer of the building.

Although we can only speculate that the apartment was spectacular when it housed the Bouviers, the listing photos prove it certainly is now. The four-bedroom pad comes with a marble gallery, a sweeping staircase, a "baronial" living room facing Park Avenue, a library with original paneling, multiple fireplaces, a state-of-the-art kitchen, a media room and staff quarters.

The apartment was reportedly damaged earlier this year when a fire broke out in the building. The fire started in Bernie Madoff associate Ezra Merkin’s sauna on the sixth floor.

Designed by Rosario Candela and built in 1930, 740 Park Avenue, is known for requiring potential homeowners to show $100 million in liquid net worth. LLNYC took a look to see who managed to make the cut in our Board Approved series.

Serena Boardman and Jeremy V Stein of Sotheby's International Realty have the listing with Tal Alexander and Oren Alexander of Douglas Elliman.
