Apartment 6D is an elegant and beautifully proportioned, corner 10 into 8.5-room home superbly situated in the heart of the Upper East Side, only one block from Park Avenue and surrounded by every convenience. Gracious and grand, the immense scale is enhanced by 10 high ceilings, abundant oversized windows, three exposures with two corner rooms and splendid light throughout. Exquisite old-world detail includes original hardwood herringbone floors, pristine crown moldings, beamed ceilings, wood-burning fireplace and built-in bookshelves. Originally a 10-room home, this apartment was reconfigured creating an open expansive corner living room, a fourth bedroom and large butlers pantry. There is a fabulous flow for entertaining with an open, bright and airy living room/library, formal dining room and grand eat-in kitchen. There are four bedrooms and three en suite full marble baths. Modern conveniences include through-the-wall air conditioning, in-unit laundry and abundant storage. The apartment shares the elevator landing with only one other home. The very large eat-in kitchen is a sunny and cheery space to both work and casually dine and includes abundant cabinetry, granite counters, built-in wine rack, professional appliances including a Sub Zero refrigerator and a very special 6-burner Garland oven with overhead broiler and industrial vented hood. A true butlers pantry was beautifully renovated with abundant granite counters, stainless backsplash, custom cabinetry, independent sink, pantry closet and laundry closet. 150 East 73rd Street is a handsome full-service prewar cooperative building built in 1923 and perfectly positioned in the heart of the Upper East Side surrounded by an array of stores, dining options and conveniences. The building features an elegant lobby with full-time doormen and a central laundry room and individual storage.
