Welcome home to Residence 5S, a refined “classic seven” apartment perfectly located on a quiet, tree-lined block just off Park Avenue. Sharing the floor with only one other unit, this bright and spacious home features four bedrooms and two-and-a-half bathrooms, with many original and elegant pre-war details. Upon entry, a gracious foyer leads to an inviting central gallery, complete with a spacious coat closet. The sun-filled, south-facing living room has a wood-burning fireplace, custom-built-ins, and a large bay window that allows for an abundance of natural light. Just off the living room, a formal dining room with another bay window offers the perfect setting for both everyday dining and entertaining. At the heart of the home, the oversized kitchen is outfitted with granite countertops, stainless steel appliances, including a vented Jenn Air range hood, ample storage, and charming exposed brick. A side service entrance adds convenience, and a nearby powder room doubles as a laundry space, complete with a stacked washer/dryer. Just beyond, a bright windowed room offers flexibility as a fourth bedroom, home office, or den. The south-facing primary bedroom has generous closet space and a newly renovated en-suite bathroom. Two additional bedrooms are tucked away in a separate wing, sharing a nicely appointed Jack and Jill bathroom. Timeless details include herringbone hardwood floors, original moldings, beamed ceilings, and brand-new radiators. Through-the-wall A/C units provide modern comfort. This pet-friendly, boutique cooperative has a recently renovated lobby, part-time doorman, and live-in superintendent. Amenities include a laundry room, playroom, bike room, and a peaceful courtyard. 106 East 85th Street is ideally located just moments from Central Park, renowned museums, and numerous choices for world-class dining, shopping, and transportation. There is a 1.5% flip tax.
