The five-bedroom, five-bathroom (plus two half-bathrooms!) apartment on the 39th floor is 10,674 square feet, and that’s not including the 709-foot wraparound terrace. It also comes with access to a 75-foot lap pool, around which Loeb can hobnob with neighbors Sting, Denzel Washington, and Goldman Sachs CEO Lloyd Blankfein; a screening room; English-oak-paneled library; formal dining room (with a private in-house chef); climate-controlled wine rooms (keep your Gewürztraminer chilled!); and a general sense of extreme self-satisfaction, especially if you pay for it in cash, as Loeb did. One issue, though: Loeb’s views of the park will be obstructed by views of Sandy Weill’s $42.4 million apartment. Well, even the rich sometimes suffer, a little.
