Looking at the photos both look beautiful. Les Jardin is more money, farther from a beach and not in Terres Basses. Maybe the owner of Nina and Pinta would offer you a discount since you would be renting both, its worth asking. It looks like Josephine is $9,600 with taxes. Josephine is represented on a lot of sites so you should be okay going with any of them unless one gives you a perk or two. Enjoy!
