Description

Beautifully Renovated, Convertible 3 Bedroom with In-Unit Laundry Room in the Heart of the Upper East Side! Apartment 11KL at 345 East 73rd Street is the one you’ve been waiting for! This beautifully renovated and seamlessly combined home offers exceptional space, flexibility, and functionality. Currently configured as a spacious two-bedroom, two-bathroom residence, the layout easily allows for conversion to a three-bedroom should the need arise. Created through the thoughtful combination of two apartments, this home features an impressive, oversized living room, separate dining alcove, an expansive primary suite and an in-unit laundry room, space rarely found in residences of this kind. A welcoming entry foyer with a large coat closet provides a proper arrival and excellent storage. Beyond, the home opens into a grand, sun-filled living and dining area featuring wide-plank maple flooring and generous proportions ideal for both everyday living and entertaining. The sleekly renovated kitchen has been seamlessly opened to the living space through a passthrough with breakfast bar seating, creating a wonderful flow between rooms. It features Caesarstone countertops, excellent cabinet and counter space, and a full suite of stainless steel appliances, including a new refrigerator and dishwasher. The gracious dining area offers excellent flexibility and can easily be converted into a third bedroom while still maintaining comfortable living space. The apartment features a highly desirable split-bedroom layout, with both bedrooms generously proportioned and thoughtfully separated for privacy. The primary suite is exceptionally spacious and includes a renovated en-suite bathroom, an enormous walk-in closet, and outstanding storage throughout. It also features a rare full laundry room complete with sink, folding space, additional storage, and a brand new dryer. The second bedroom, formerly its own primary bedroom, is located on the opposite side of the apartment, offering exceptional privacy and substantial closet space. A second full bathroom is conveniently located in the hallway. The Morad Diplomat is a full-service cooperative offering a 24-hour doorman, live-in superintendent, a tranquil rear courtyard, full laundry room, and onsite parking and storage (both subject to waitlists). The building has also recently completed a number of significant capital improvements, including a new water tower, modernized elevators, a new boiler system, and beautifully renovated hallways. The location can’t be beat, with neighborhood favorites such as Campagnola, Up Thai, Second Avenue Deli, and the newly opened Westville just moments away. For fitness enthusiasts, both New York Sports Club and Equinox are conveniently nearby. Transportation is effortless with the 72nd Street crosstown bus and the Q train right outside your door along with the 6 train just a short walk away.
