Meticulously maintained inside and out, the Mayo-Keene House (circa 1834) has been lovingly preserved while thoughtfully expanded & updated with every modern feature. Offering over 4,000 square feet of finished living space, this expansive 3-bedroom, 5.5-bath residence seamlessly blends historic character with today's quality craftsmanship. Inside, generous living areas allow everyone to enjoy their own space and privacy. A chef's kitchen featuring a Wolf gas range, dual Wolf ovens, two islands, built-in beverage refrigerator drawers, and custom cabinetry-perfect for cooking and entertaining alike. Enjoy radiant floor heating in all five bathrooms and the inviting four-season sunroom, where you can take in tranquil views of Rock Harbor and Rock Harbor Creek. Just a short stroll out of the driveway brings you to Dyer Prince Beach, where you can experience the beauty of Cape Cod Bay, or launch your boat nearby at the Eastham side of Rock Harbor.
