Spanning 3,624 square feet, this 4bedroom, 4.5bath residence offers exceptional versatility, perfect for full-time living, a luxurious vacation retreat, or hosting extended family & guests. The home is being offered fully furnished, allowing for effortless enjoyment from day one. Each bedroom is spacious and thoughtfully designed with its own en suite bath, providing privacy and comfort throughout. Soaring ceilings, transom windows, and original Dade County pine walls honor the home's heritage, while modern upgrades including updated systems, surround sound, and security features blend historic charm with contemporary convenience. The chefs eat-in kitchen is both elegant and functional, featuring Viking appliances, granite countertops, and a layout ideal for entertaining. Sun-filled living spaces flow beautifully through expansive impact glass doors to the outdoors, where a heated saltwater pool and separate hot tub are surrounded by lush tropical landscaping, irrigation, and ambient lighting creating a private island oasis. Upstairs, the primary suite is a true retreat, showcasing vaulted ceilings and a spa-inspired bath with a soaking tub, multiple shower heads and dual vanities. An additional upstairs en-suite offers its own private entrance and balcony, providing flexibility for guests or extended stays. Just one block from Duval St. & the iconic Southernmost Point, with covered off-street parking, it's within walking distance to the very best of Key West's dining, nightlife, & culture.
