Description

New look to match new price. This impressive and private 5th floor residence (approximately 4184 sq. ft) at 823 Park Avenue, an exclusive yet welcoming pre-war full service boutique condominium at 75th and Park in proximity to Central Park, a bevy of schools and world renowned cultural institutions, offers the highest level of luxury, service and elegant day-to-day living. The private elevator vestibule leads to a gracious entrance gallery where a show-stopping double-sized, western facing, sun-kissed living room with a gas fireplace and tree-lined views over Park Avenue beckons. Adjacent to this signature room (and ideal for remote work days or intimate entertaining) is the most alluring mahogany paneled corner library with its own gas-burning fireplace. To the north is a commanding formal dining room easily seats 16 to 24 people and a spectacular eat-in chef's kitchen complete with prep island, top of the line viking and subzero appliances will simply delight. Importantly, the discretely placed powder bath off the hall serves for the comfort of one's guests. The private wing of the residence is pin-drop quiet. With two exposures, the grand sized primary bedroom offers pleasant garden views and closets galore! Its spa-like bath outfitted with neutral hues of marble has a separate shower, glorious soaking tub (dare I say easily fits 2) and double sinks is an oasis to begin and end one's day. 4 additional bedrooms (and additional 3 full baths are each sporting nickel fixtures by Waterworks) that offer the utmost flexibility and/or room to grow. Other important features include Central Air Conditioning, washer/dryer, 10' ceilings, and herringbone hardwood floors. 823 Park Avenue, built in 1912 by Pickering and Walker, this pre-war condominium was completely redevelopment in 2007. Its exclusive 12 residences has the most attentive staff, a natural lit state-of-the-art fitness center and private storage. Pets are welcome and finance as you wish. Your search is over! Some photos are virtually staged. Please note: showings are permitted Mon-Fri 9AM-3:30PM only.
