Diane's is right in the action, walking distance to everything. Diane is one of the famous Auxillou sisters who have adjacent condo-tels on the front right near the water taxi. I have not been inside all of the sister's rooms, but they are generally VERY nice for Caye Caulker and you get what you pay for...
