Cityfile: New York's Most Notable and Influential

• Bob Weinstein and his wife Annie Clayton are reportedly looking for a buyer for their five-bedroom apartment at the Beresford. The 6,500-square-foot duplex is "quietly" being offered for "around $34 million" by Brown Harris Stevens broker Ileen Schoenfeld. No need to worry about the couple being homeless if they manage to unload the apartment: In addition to a townhouse on West 70th Street, which they picked up for in May for $15 million, the Weinsteins also own a one-bedroom on West 67th Street and a condo at Astor Place.

• Retired hedge fund manager Michael Steinhardt has sold his two-bedroom apartment at the Museum Tower. He and wife Judy won't be moving, however: The Steinhardts split their time between an apartment at 1158 Fifth Avenue and a massive estate in Bedford. [Cityfile]
• Charles Martin Jr., the CEO of Vanguard Health Systems, has picked up a pied-à-terre. The Nashville-based exec purchased a four-bedroom duplex at 155 West 15th Street for $6.675 from Blackstone senior managing director Neil Simpkins and his wife Miyoung Lee. [Cityfile]More

The Sun has had financial problems since day one and it never made much headway in the circulation department. This time, though, it looks like it could be the end of the line: The paper even posted an account of its problems on its website. (Perhaps in the hope that another super-conservative, Jewish billionaire will turn up with his checkbook.) So why are the Sun's current backers—including Bruce Kovner, Tom Tisch, and Michael Steinhardt, left—giving up? They've got plenty of other stuff to worry about, that's why. More
