## Description

### Agent Description
Enjoy island living at its finest in this historic Quartermasters at Diamond Cove on Great Diamond Island. This 3-bedroom, 2.5-bath home offers antique hardwood floors, soaring ceilings, exposed beams, and a cozy wood-burning fireplace. The kitchen features stainless steel appliances and granite countertops, and the desirable first-floor primary suite adds comfort and convenience. A private deck with water views extends your living space outdoors. Just a short stroll away are the island's restaurant, marina, and private beaches, along with endless opportunities to explore the surrounding islands and boating destinations or head into Portland for its vibrant dining and shopping scene.  Diamond Cove residents enjoy outstanding amenities, including a heated pool, tennis and pickleball courts, fitness center, indoor basketball court, antique bowling alley, private beaches, and wooded walking trails. With convenient year-round ferry service from Portland running multiple times daily and on-site association staff, island living in Maine has never been easier--just in time for summer!
