The townhouse where the financier Jeffrey Epstein is accused of engaging in sex acts with underage girls is one of the largest private homes in Manhattan, a short walk from Central Park.

The seven-story residence at 9 East 71st Street, between Fifth and Madison Avenues, sprawls across 21,000 square feet and has five bathrooms, a two-story reception room and many bedrooms, including three three-room suites on the fourth floor.

It also has a heated sidewalk in front to melt the snow during the winter months. On the second floor is a mural that Mr. Epstein had commissioned in recent years: a photorealistic prison scene that included barbed wire, corrections officers and a guard station, with Mr. Epstein portrayed in the middle.

“He said, ‘That’s me, and I had this painted because there is always the possibility that could be me again,’” said R. Couri Hay, a public relations specialist invited by Mr. Epstein to a meeting at his home and to view the mural three months ago.
