Douglas Elliman brokers Shannon Dunne and Tristan Harper have the listing, at 170 East 77th Street between Lexington and Third avenues. The two-bedroom, two-bathroom unit, which spans 1,100 square feet, is asking $1.8 million. There are two terraces, one of which is on the roof.

In 2008, Ponzi schemer Bernie Madoff’s niece, Shana Madoff, and her husband, Eric Swanson, put a $4.195 million bid on a condo at the building, but withdrew the offer on December 11, the day Madoff was arrested, saying one of the bedrooms was too small. [NYP, 2nd item]Mark Maurer
