The mansion known as Dunnellen Hall is on 40 acres in Greenwich with distant views of Long Island Sound.
The Greenwich Time reports (http://bit.ly/1rU6Ntn ) that the mansion features an entry room with an elevator and limestone walls and flooring, a 45-foot living room, a library, nine bedrooms, and a game room.
The hotel owner and real estate baroness served 21 months in prison for evading federal taxes by billing her businesses for mansion renovations. Called the "Queen of Mean," she died in the mansion in 2007 at age 87.
In the renovation, a service kitchen, rooms for staff and three swimming pools were removed. An audio-visual system and new landscaping were added.
