We rented house on the North side (French) and drove the insland a lot. Its a cowboy town on the roads! House was cheap for 4 of us; pool, etc. We went to a little island, maybe it is the same you mentioned.
We took the plane over to SABA - you need to go there - very laid back and cool feel. I enjoy Saba much more than Marteen. The vista from Saba is great! Standing on a 1600' cliff looking over the other islands.. FYI Marteen there is pot everywhere, our taxi driver had it in his visor and it kept falling out.
