Oceanfront w/ Dock, Kayaks, Hot Tub & Secluded

Buchanan Keys Cottage Take a step back into “Old Keys” living.

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”.
