Experience riverside luxury at 5478 Mariners Cove, where smart home technology meets elegant design in a beautifully upgraded waterfront retreat. Tucked away on a secluded cul-de-sac, this 3-bedroom, 2.5-bath residence offers privacy and tranquility while remaining just minutes from everyday conveniences and easy access to Downtown Jacksonville. Inside, the home showcases new flooring throughout, new kitchen cabinetry and countertops, and updated bathroom vanities, creating a fresh, modern feel. The spacious family room makes a striking impression with soaring 20-foot ceilings, an abundance of natural light, and a dramatic two-story brick fireplace that serves as the heart of the home. The chef's kitchen is designed for both functionality and entertaining, featuring a built-in ice maker and trash compactor. The custom-built primary closet and two built-in safes - one in the primary bath and a floor safe in the closet-provide both practicality and peace of mind.
