The oversized primary suite has ample space for king sized furniture and features a deluxe custom California Closet dressing room and a spa-like bathroom with Brizo Chrome fixtures, custom glass shower door, rain shower and full height glass mirrored/medicine cabinet. The balcony off the primary bedroom is the perfect touch, inviting you to enjoy your morning coffee or a sunset cocktail.
The cherry on top of this incredible home is the versatile second bedroom which can be used as a den, guest bedroom, library or home office with custom wall paper, another large walk in-closet and full size washer dryer. The accompanying guest bathroom was expertly designed with Premium Polished tile and Brizo Brushed Nickel fixtures.
Every inch of this home reflects a commitment to craftsmanship and design, creating a rare turnkey opportunity in one of Manhattan's most sought-after neighborhoods.
