FLATIRON MAGIC

Whether you like to entertain or relax, you’ve found your next home in this beautiful prewar building, located off Fifth Avenue in the Ladies’ Mile Historic District of Flatiron. Enter through a keyed elevator directly into the loft’s spacious foyer and you can’t miss the 10-foot ceilings and wide-plank hardwood floors. Cook something special in the beautiful Valcucine kitchen with Miele and Sub-Zero appliances including a dual-zone wine fridge, espresso machine and warming drawer, and then create the perfect evening in the tremendous living and dining room space featuring five oversized, southern-facing windows. The natural light is fantastic.

The remarkable length of this apartment around 80 feet means that the two bedrooms feel completely secluded, giving you plenty of peace and privacy. There’s an abundance of daytime light in both rooms thanks to large north-facing windows. Each bedroom has an en-suite, full bathroom with heated floors and rain showers, while the master also has a double-sink vanity and a deep-soaking bathtub with soothing waterjets as well as a walk-in closet. Transform the large third room into the space that’s right for you, whether it’s an office, den or nursery. California closets abound.

Work, play and unwind in complete comfort with luxurious custom lighting, multi-zone climate control, an ample walk-in laundry room and plenty of storage space in the apartment and the basement. There’s a 24/7 gym, and the building features a rooftop patio outfitted with a gas grill and furniture for entertainment. Building staff includes a dedicated superintendent, porter and doormen.

Step out onto 20th Street and youll relish the simply unbeatable location. Madison Square Park and Union Square Park are within walking distance. You’re encircled by a host of renowned restaurants, French-inspired cafes and home goods purveyors, as well as Eataly, Whole Foods and Trader Joe’s. You’ll be quickly on your way to anywhere in New York City given easy access to the L, N/Q/R/W, B/D/F/M, 1/2/3, 4/5/6 and the PATH train.
