According to the New York Times, sources close to Bloomberg say she paid near the $4.15 million asking price for the apartment, which is housed in a historic prewar Central Park West building. Bloomberg reportedly looked at 150 apartments before settling on 101 CPW.
The New York Observer writes:
According to a StreetEasy listing, which went into contract in July and slipped off the market on November 5, the old apartment has been newly updated "by one of New York's premier interior designers." There are double-pane thermal windows, new appliances and fixtures, all with well preserved prewar details, such as "Oak herringbone walnut-stained hardwood floors and beautiful large custom Mahogany doors in every room."
