Google maps will show you the locations on both sides. I've had friends (medical students on island) tell me that in case of an emergency, drive, walk or crawl to the French side rather than the Dutch side. I was surprised at the level of care on the French side on the one occasion I really needed it - I even got a CAT-Scan for around €400 and have been told that this can cost on average over $3000 in the USA!
