Welcome to the Westchester, one of Washington's storied cooperative communities that is prominently featured in the book "Best Addresses", James Goode's history of the city's most historic and architecturally significant apartment houses. With stunning Art-Deco details; gracious public spaces that were designed by the legendary New York-based designer Dorothy Draper; and lovely, manicured common grounds where Member-Owners can relax and enjoy beautiful natural surroundings, the Westchester is a quiet oasis in the city and an elegant place to call home. Apartment 609-A is a large (1100+ square feet) 1-Bedroom/1-Bath unit that will afford a buyer with an opportunity to creatively modernize and restore the space according to their personal tastes and design ideas, and it is priced to refect the unit's current condition. It features high ceilings, a large Living Room, a separate Solarium with northern and western exposures and a stunning direct view of the National Cathedral, a separate Study that could be used as a dining area or as a guest bedroom, and a generous Bedroom with a walk-in closet and a cedar-lined clothes closet. The monthly coop fee includes property tax, utilities, landscaping and grounds maintenance, and 24/7 security personnel. Amenities at the Westchester include: a Concierge desk, the Westchester Market (well-stocked and includes a Deli), a Valet for dry cleaning and full alteration service, Guest Suites that are available for rent on a nightly basis, a Fitness Center, a Library, onsite parking, and a Service Department to assist residents with porterage and minor in-unit maintenance requests. The Westchester is only a few blocks from Cathedral Commons , where you will find Giant, CVS, Starbucks, and top-flight restaurants including Two Amys, La Piquette, Raku, Barcelona, Heritage India, and Cactus Cantina, among others. At nearby Foxhall Square, you will find: Chef Geoff's, Al Dente, Wagshal's, medical offices and Voorthuis Opticians. Metro Bus service to downtown DC is available on Cathedral Avenue at the front entrance to the property, and to Georgetown and Chevy Chase along Massachusetts and Wisconsin Avenues, three blocks away. If you are looking for grand space that is ready for your special touches, and that offers beautiful surroundings and a quiet refuge in the city, you'll find it at the Westchester!
