The storied River House co-op has historically been home to many a boldface name—its roster of current residents includes Uma Thurman, Henry Kissinger, and Wilbur Ross—but one of its tenants now wants to part ways with their pricey pad.

Lady Lynn Forester de Rothschild, the wife of British banking scion Sir Evelyn de Rothschild, is selling a duplex apartment in the building that she’s owned for two decades, according to the Wall Street Journal. The six-bedroom, seven-bathroom apartment is listed for $22.5 million; Erin Boisson Aries and Nic Bottero of Christie’s International Real Estate Group have the listing.

In total, the apartment has 17 rooms: The lower level of the duplex is where the common spaces—a great room, library, dining room, and sun room (which leads out onto a terrace)—are located, while the upper level is home to the bedrooms, a great hall, and a “master sitting room” that’s adjacent to the master bedroom (which itself has splendid East River views).

According to the WSJ, Forester de Rothschild hired Michael S. Smith, an interior designer best known for working with Barack and Michelle Obama to decorate the White House, to spruce up the place after she moved in. He went for what he says is an “English country house” vibe in the apartment, and added bits of visual interest like 18th-century wallpaper in the dining room.

The 7,000-square-foot apartment is one of several that are currently on the market at River House, which has a reputation for being very hard to get into. (Diane Keaton, Gloria Vanderbilt, and Joan Crawford were all reportedly turned down by the building’s notoriously finicky board.) The purchase price also includes access to the River Club, a members-only club that was once marketed as a 62,000-square-foot, $130 million mansion. (It was pulled off the market in 2014 so the building’s residents could continue to use it as their own uber-exclusive hideaway.)
