In Massachusetts Avenue Heights, this limestone Beaux Arts estate just landed on the market with a long history of hosting politicians and entertainers and a long history as one of the most expensive houses on the Washington, D.C. market. In 2010, entrepreneur, philanthropist, and "Patron of Diplomacy" Adrienne Arsht purchased the property for $8.2 million, making it the most expensive property sold in the District by August of that year, according to Washington Life. Arsht is a fervent supporter of the arts and has donated $5 million to the Kennedy Center as well as $56 million to non-profit organizations from Miami to Manhattan, reported The Washington Post. In the Embassy Row mansion, she has hosted diplomats, politicians, entertainers, and even the former prime minister of Spain José María Aznar. The seven-bedroom estate is on the market for $12 million and comes with 10,300-square-feet of space, or $1,165 per square. While the abode was constructed in 1927, all of the windows and doors were replaced only two years ago. Some of the most luxurious highlights to the abode include a pool, 12-seat theatre, caterer's kit and staff quarters, and marble terraces with views of Rock Creek Park.
