Thanks all, I appreciate the input. The seaweed smell was certainly something else I hadn't considered! (I can actually see it accumulated in cul de sac on Google Earth) I found the same AirBnB villa listed on VRBO and got more reviews too showing it is in a small gated neighborhood called Park View behind the pharmacy and feel a bit better about it. There are so many beautiful villas on SXM, but I am always a bit cautious. Last visit to GCBC in fall there was still too much construction on the new building by petit plage, but supposedly that shifted to inside work now.
