Enjoy house-like proportions, total privacy, and an unbeatable location in this oversized 2 bedroom plus large home office prewar condo. Unit 5A presents a gracious lifestyle from the outset with private keyed elevator access directly into the apartment and an expansive gallery separating the entertaining and bedroom wings. Nearly 10-foot ceilings add to the loft-like scale of the side-by-side living and dining rooms which overlook landmark Flatiron architecture through a wall of huge South facing windows. Custom built-ins, finishes, and recessed lighting further underscore the design quality evident throughout this residence.

A top-of-the-line kitchen by Valcucine of Italy features plenty of elegantly hidden storage space as well as a Miele and Sub-Zero appliance package that includes add-ons such as a wine fridge, coffee system, and stove-top water faucet. The two bedroom suites and large home office are complimented by generous closet space and three full baths, including a spa-like master bathroom with separate water closet, soaking tub with built-in flat screen TV, double vanity, and radiant heat floors.

The unit also includes separate private storage. Please note that there is currently a monthly assessment of $352 related to building maintenance components, elevator, chiller, and air filtration work which will be re-assessed at the end of the year.

The building features a part-time doorman, La Palestra designed gym, and beautiful roof deck with grill. Madison Square Park, the finest retail of lower Fifth Avenue, cafes and outdoor seating, Eataly Market, and the nearby Chelsea, NoMad, Greenwich Village and West Village neighborhoods are all steps away.
