With a wall of southern windows throughout, Apartment #10D is a beautifully maintained, graciously proportioned one bedroom/one bathroom home.  This traditionally inspired  residence evokes classic prewar style: substantial crown moldings, detailed baseboards, paneled doors, and rich oak floors. Both the bathroom and kitchen have been recently renovated. The windowed kitchen features abundant wood cabinetry, stainless steel appliances, stone countertops, and tiled backsplash. In addition, there is abundant storage in the seven closets.       Built in 1967, 12 Beekman Place was designed by the prolific Manhattan architect H.I. Feldman. Residents of this full-service cooperative enjoy the services of a full-time door staff and resident manager, on-site parking garage, bike storage, central laundry room, and planted garden patio. Pets, pieds-à-terre ownership, and 65% financing are permitted. With quiet tree-lined streets, Beekman Place retains its reputation as one of the desirable places to live on the East Side of Manhattan.
