The most expensive apartment in Manhattan history has sold to a 22-year-old woman. Ekaterina Rybolovleva, the daughter of Russian billionaire Dmitriy Rybolovlev, has paid $88 million for former Citigroup Chairman Sandy Weill’s 6,744-square-foot, 10-room condo. Rybolovleva is a student at an undisclosed U.S. university and plans to stay at the condo when visiting New York.
