The oversized primary bedroom offers two large closets and a renovated ensuite bathroom with a spacious walk-in shower and an additional entrance from the hallway for added convenience. Additional highlights include hardwood floors throughout and freshly painted interiors. Building amenities include a full-time doorman, beautifully landscaped courtyard patio, common laundry room, bicycle room, and storage (waitlist). Enjoy a short commute to Grand Central Terminal via Metro-North. Parking is available by waitlist, and residential street parking is available through the Village.
