Luxury condominiums on Park Avenue are usually exquisite, and the apartments for sale at 823 Park Avenue are no exception. The renovated pre-war building in the heart of the Upper East Side boasts ten full-floor condominiums, each at over 4,100 square feet, meaning that while you could use the state-of-the-art fitness center downstairs, you're probably fine just running the length of the condo a few times. Of course, each luxury condo features views overlooking Park Avenue, gas-fired fireplaces and a bar capable of holding forty-six wine bottles, so you might never get around to exercising. A private library complete with wood paneling, built-in shelves and a fireplace compliments each condo at 823 Park Avenue, so residents can spend evenings with their favorite paperback or e-book, or newspaper. A service elevator leads directly to the eat-in kitchen, for grocery delivery ease, and a center island allows for a more professional prepping experience. A professional-style Viking range insures quality meals, and the formal dining room offers a downright fine-dining experience. These Park Avenue luxury condos come with a bounty of amenities, from the more standard doorman-and-concierge benefits to a live-in superintendent, Greek Revival lobby, and double sinks in every apartment. Each full-floor condominium for sale includes both a master bath and bedroom, both loaded with contemporary touches and refined designs. And with Central Park and some of the city's most notable museums nearby, including the Metropolitan Museum of Art, the area surrounding 823 Park Avenue is as enviable as the condos themselves.
