Description

Located on the quintessential tree-line block of East 64th Street between Park and Lexington Avenues, this B-line, 10-into-8 room apartment has three-bedrooms and three-and-a-half baths. A private elevator vestibule opens into an expansive gallery setting the tone for the apartment’s gracious proportions and elegant interiors completed by the renowned interior designer, Clare Fraser. Thoughtfully positioned off the gallery is a suite of well-appointed entertaining rooms as well as well-placed Powder Room. Generously proportioned, the Living Room, with a beautiful fireplace, allows for several seating arrangements. It is further complimented by three oversized, east-facing windows overlooking Lexington Avenue. From the Living Room, one enters a handsome, knotty pine wood-paneled library complete with custom millwork shelving and two east-facing windows. Perfect for entertaining, a pantry can be accessed from the Library and features a wet-bar and ice machine as well as a door connecting to the Kitchen. In addition to the Living Room and Library, the apartment’s formal Dining Room is accessed from the gallery and features fabric upholstered walls and an intricate inlaid patterned wooden floor. Additionally, the Dining Room benefits from two large windows with western exposures. The apartment’s windowed, eat-in kitchen has been previously renovated and features high-end appliances including a Viking range, Bertazzoni refrigerator, and Bosch dishwasher as well as custom-cabinetry and ample counter-space. The apartment’s three bedrooms are located along a private hallway separate from the entertaining rooms. The first bedroom, currently configured as an Office, is well-sized and has an ensuite bath. The apartment’s second bedroom is traditionally decorated and benefits from several millwork closets as well as two large windows that offer southern and western exposures. This bedroom is complimented by an ensuite bath with walk-in shower. The Primary Bedroom is located at the end of the hallway and is generously scaled and features three windows allowing for both northern and western exposures. From the ensuite primary marble bath, one enters an amply sized windowed Dressing Room. If desired, both the Primary Dressing Room and the adjacent walk-in closet may be combined, with approval, to create a Fourth Bedroom. Additional features of this refined apartment include custom architectural molding, hardwood floors, beautiful mahogany three-panel doors, and ceiling heights over 9 feet. The apartment also benefits from individually controlled through-the-wall air conditioning units and a washer dryer. Built in 1927 by noted architect Kenneth M. Murchison, 133 East 64th Street is a well-regarded, prewar cooperative offering a full-time doorman, a live-in resident manager, and private storage. The cooperative permits pets upon approval and up to 50% financing. The building has a 2% flip tax.
