“As far as where a billionaire would want to live, this is second to none,” Massey Knakal’s Guthrie Garvin told the Observer. “This is one of the most desirable townhouse blocks in the city. With its location near Central Park, 25-foot width, beautiful façade and over 11,000 square feet, this is an opportunity to create one of the finest mansions in the city.”

Garvin was not able to comment on the seller. [NYO] — Zachary Kussin
