Welcome to 657 Cardium, tucked along one of Old Sanibel's last quiet shell streets, where cottage-style homes, sea-grape hedges, and bicycle bells still set the pace. This Sanibel Shores address puts you a short stroll from the Gulf and its legendary shelling, with Periwinkle Way and the island's best dining just minutes away by bike. Inside, four bedrooms and three full baths unfold in an easy single-level layout with plenty of natural light, giving the home the breezy, unhurried feel that people come to Sanibel for in the first place. This fully renovated, newly furnished home has a coastal modern feel throughout with light flooring, impact windows and doors, custom bathrooms with oversize showers, and a chef's kitchen. The kitchen features beautiful cabinetry, modern stainless steel appliances, a custom backsplash, and quartz countertops, while the back deck overlooks a large yard. A new roof and all-new appliances make this a worthwhile investment! Whether you are looking for a full-time island residence, a seasonal retreat, or a rental-ready property, 657 Cardium delivers the Sanibel lifestyle at its most authentic: no high-rises, no hurry, just shell-lined streets and Gulf breezes.
