We stayed for a week in June and it was a very quiet, secluded, beautiful spot on the island. The staff was incredibly friendly and accommodating. The view was absolutely breathtaking. If you're looking for a place to completely de-stress and to completely get away from the world, this is it.
We spent most of our time eating at the hotel. There aren't a whole lot of options in the area to eat. And the places that are around are overpriced and the food is so-so. The food at Hotel Marquis is good and is cheaper than what you'll find around in that part of the island.
We only traveled to Marigot once and it was enough for us. If you want to get around, the Hotel Marquis can recommend good taxi drivers. Just expect to pay a little bit of money due to the location of the hotel.
We loved it. And we would absolutely go again.
