850+ SQFT PRIVATE TERRACE
Welcome to the Penthouse at 24 East 21st Street, a private oasis with 4 Beds and 4.5 Baths in prime Flatiron. Stepping off the keyed elevator you are immediately greeted by the expanse of the 18+ foot ceiling, sunny skylights and endless living space. The floor-through, 40 foot long, great room provides a grand setting for both relaxing and entertaining, enhanced by sunny southern and northern views. The newly renovated, eat-in, kitchen is a chef's dream, featuring quartz countertops, Bilotta cabinetry, and top of the line appliances including a Sub Zero refrigerator, Viking range, and two dishwashers - a space that is as functional as it is beautiful. Ascend up the glass encased stairs to enter the large private terrace above. With over 850 sqft, beautifully landscaped, and a three season cabana, this terrace is the perfect private getaway and excellent for entertaining. A breathtaking glass enclosed gallery leads to the private wing, anchored by an expansive media and family lounge with a full bar - an exceptional bonus space ideal for entertaining, work, or relaxation. The south-facing primary suite is a serene retreat featuring dramatic ceiling height, electric shades, large walk-in closet, and a luxurious marble bath with double vanity, soaking tub, and separate shower. Two additional generously proportioned bedrooms offer custom closets, with one en-suite bath and a separate full bathroom off the gallery that also houses a Miele washer and dryer. On either side of the entry foyer there is a powder room for entertaining guests and an additional staff room outfitted for storage with a wine fridge and an en-suite bath. Other features of this apartment are central AC with three zones, hardwood flooring throughout, gas fireplace and a juliet balcony. Located just off Park Avenue South, 24 East 21st Street sits at the crossroads of Flatiron, Gramercy, and NoMad - surrounded by acclaimed restaurants, Madison Square Park, premier fitness studios, and convenient transportation. The building consists of eight full floor residences with two private keyed elevators. There are also keyed storage lockers in the lobby. This penthouse presents a rare opportunity to own a truly special residence in one of Manhattan’s most vibrant and enduring neighborhoods.
