## Description

### Agent Description
Welcome to Casa Sirena, a refined waterfront retreat in Marathon offering comfort, privacy, and strong investment appeal. This five bedroom, three bath home includes a convenient outdoor pool bath and is ideally positioned with water frontage on two sides. Boaters will appreciate 100 feet of durable composite dockage, a jet ski lift, and a private boat ramp shared with just one neighbor. The home enjoys close proximity to Boot Key Harbor, with easy access to waterfront dining by boat, as well as a straightforward route to the Gulf via Knight Key Channel and immediate Ocean access. The surrounding Vaca Key and Boot Key provide a natural buffer, offering added protection from the elements. Outdoor living is central to the property, with lush tropical landscaping, a saltwater pool, tiki hut, and expansive wraparound patios accessible from all rooms. Inside, the open floor plan connects the living, dining, and kitchen areas, creating a comfortable and functional space. The kitchen is equipped with high end appliances suited for everyday use or hosting. Additional features include a spacious two car garage with ample storage, an extra washer and dryer, refrigerator, freezer, and workbench. The home is offered fully furnished and turnkey, ready for personal use or as a vacation rental. Privacy fencing, a security system, and gated dock and ramp access complete the offering.
