Welcome to Casa Mar Azul, a one-of-a-kind oceanfront estate located along the iconic Old Highway in Islamorada - a rare offering with 200 feet of oceanfront shoreline, a private jetty with dockage, and breathtaking panoramic views of the Atlantic Ocean. This elegant coastal retreat blends indoor-outdoor living with an open floor plan and soaring vaulted tongue-and-groove ceilings that bring warmth and character to the airy living space. Floor to ceiling windows and doors lead to an expansive open terrace, where unobstructed ocean views take center stage and sea breezes invite total relaxation. Upstairs, you'll find two spacious bedrooms and two full baths, each thoughtfully designed for comfort and ease. A versatile bonus room opens to a covered lanai that leads directly to your own sandy beach - the perfect spot for morning coffee or sunset gatherings. The private jetty stretches 200 feet into the turquoise waters and offers dockage at the end, ideal for boating, fishing, or simply soaking in the serenity of the sea.
