Celebrity event planner Jennifer Zabinski has listed her three-bedroom, 3.5-bathroom apartment on Manhattan's Upper East Side for $3.99 million. Located in an "impeccably maintained prewar cooperative," the apartment offers 2,600 square feet of living space. The listing also includes plans showing how the unit could be reconfigured to add an extra bedroom. The property, which is listed with Catherine Juracich of Corcoran SoHo, is located on East 73rd Street and features an elegant aesthetic that would be at home in glossy magazines. The building itself also offers impressive amenities, including a fitness center, storage units, and a laundry room.
