FYI incase anyone is interested, The Fishers (they make Sangrea(sp?) de Maya, live in Tres Cocos with a nice view of the Palapa bar, and they are renting out the bottom of their house...thinks its a two bedroom, 1200sqft. I believe the rent is only $600us per month.
Its a nice area but not great if you plan to party every night as the ferry stops at 8pm. You can always take a water taxi back to the Palapa bar though
When there is a will there is a way!!!
