One of the Real Estate Things To Watch in the coming year was going to be the competition between the city’s five listings asking $100 million or more. But one of those listings, the $125 million penthouse atop the Pierre Hotel owned by the widow of stock investor Martin Zweig, has already dropped out of the $100 million race, cutting its price by $30 million, down to a paltry $95 million. Despite the 24 percent discount, if the residence got its full ask it would still set a city record, and remains a long shot. But an impressive long shot nonetheless, encompassing the three top floors of the famous hotel, with 16 rooms including the living room, which, according to the brokerbabble, “is considered the most magnificent privately owned room in the world.” It carries monthly charges of $42,720.
