The furtherest out we've stayed is Marigot and unless you like the thrill of driving in St Barts at night, I would opt for Flamands over Deve. We've stayed in the Roc Flamands complex before in Villa Affriole. The units offer beautiful views and are right around the corner from Petit Columbe and Les Bananiers; the walk to Flamands beach wasn't bad. "8" looks like the end unit, so it should be more private than the other units there. I love the Marigot/Grand Cul De Sac area of the island too, we've stayed there three different times, but we usually travel with our kids and I much prefer driving to and from a villa that's closer "in town."
