We have stayed many times at a villa in Terres Basses at Baie Rouge. That area is just at the border and had no problems i understand getting in or out plus the villas are normally behind their own gated area with their own good security. Personally I’d feel fine staying in that area as it’s just barely within the border and just a few minutes back to the Dutch side. To far into the French side could be a problem to get out if something else happens. We love both sides and pray things we get resolved.
