515 Park Avenue only has 30 apartments on 43 floors. The limestone, cast stone and brick tower, designed Frank Williams & Associates, is a Post-Modern condo building that seeks to carry on the Avenue's predominantly Italian Renaissance-palazzo (co-op) tradition, serving as clear proof of Zeckendorf's success at marrying prewar-inspired design with thoroughly contemporary layouts and amenities.The building has the white-glove service one expects when living on fabled Park Avenue with full-time doormen, concierges and valets. However, you also get the 21st-century amenities usually associated with luxury new developments: a gym with state-of-the-art equipment, a dining/meeting room with a fully-equipped catering kitchen, and a library, all for residents only. In addition, there are private, climate-controlled wine cellars and individual storage rooms.The prewar-inspired design extends into 515 Park Avenue 5A where, from the moment you open the door, the herringbone floors harken back to the craftsmanship of a bygone era, while the light stain immediately tells you this is a contemporary apartment. The generously-proportioned rooms and high ceilings enhance the airy feel of the home, and expansive windows invite light and great views of Park Ave.Originally a 3-bedroom, 3.5-bathroom residence, 515 Park Avenue 5A is currently configured as a 2-bedroom (with en-suite baths in each bedroom) separated by an oversized entry gallery for maximum privacy.The home also has an oversized eat-in chef's kitchen with premium commercial-grade appliances and luxury features , including a Subzero refrigerator, tiled backsplash, marble countertops and custom-made windowed cabinetry.515 Park Avenue 5A's generous library and formal living and dining rooms-all brightly lit by oversized windows-make it an ideal place to entertain, or just to spread out and relax.For entertaining, the apartment has a half bath for guests, a laundry room with washer/dryer in-unit, and a kitchen that comes with a service entrance and direct elevator access.Additional recent upgrades to 515 Park Avenue 5A include fine woodwork throughout, individual climate control and wiring for surround-sound stereo systems.Despite its closeness to the Midtown Business District, the location of 515 Park Avenue 5A is relatively quiet while being close to many famous stores, boutiques, restaurants and cultural institutions. There is excellent public transportation within a few blocks.And of course-how can one overlook that Central Park is near enough to have Central Park views from the living room?
