    What's special

    The attention to detail and fine craftmanship in this spectacular historic home can be appreciated for its age and lasting beauty, while modern enhancements provide all that is needed for comfortable living today. Dade County pine walls, Brazilian cherry floors, high ceilings, hand crafted moldings, and wraparound porches encompass 3,392 sf of this Key West ''Grand Dame''. The first floor includes the living room, dining room, half bath, and chef's kitchen open to the expansive family room with multiple French doors leading to the entertainment deck with oversized pool and outdoor shower. Two large ensuite guestrooms and a master suite with soaring beamed ceiling and balcony overlooking the pool completes the second floor. A private entrance guest apartment occupies the third floor.

    This property is off market, which means it's not currently listed for sale or rent on Zillow. This may be different from what's available on other websites or public sources.
