Oceanfront w/ Dock, Kayaks, Hot Tub & Secluded

Buchanan Keys Cottage Take a step back into “Old Keys” living. Once Upon A Tide; there was a sense of tranquility & peacefulness found throughout the Keys, like the one you will uncover when choosing to stay at this private, serene, 1/1 oceanfront cottage. Located on Grassy Key, this beautiful home is just 10 minutes from the City of Marathon. Far enough to be away from the hustle & bustle, but close enough to make a grocery/store run a “Keys breeze”.
