Wonderful hotel with open, beautifully designed public areas. Breakfast is served inside and outside. The pool is OK. The room in a small cabin was nice, well-designed. There was a view of the bay from the room. Only downside was the somewhat small shower that wetted the toilet and exit to the room. Road access is confusing and GPSs may misguide. The last couple 100 metres are pretty rough but can be done carefully with any rental car. Just go really slowly around the potholes. What you get is a quiet location. Recommended.

My wife and I stayed in one of the garden view rooms with a small private pool. The room was very nice and had a very large covered veranda with a kitchenette with everything you would need to fix a meal. There was a small room next to the pool with a second bed, shower, and toilet. Breakfast was very good with a large variety of fruits, pastries, and cooked eggs, all served at your table. We had a choice of two fixed menus each night, both of which were very good if you like deluxe French style cooking, and of course a bit on the expensive side.
The hospitality and service of the manager and his staff could not have been better. We got lost coming in at night and did not arrive until 10 PM, after the kitchen was closed, but they still prepared a meal for us. The only downside to Hotel Plein Soleil is the rough and twisted road getting there. Postal addresses on Martinique rarely work on Google maps, or the GPS in our car. We discovered that if you enter the town near your destination and then expand the map the hotels, restaurants, and other attractions usually appear.
Le Francois was well situated for us to visit things in the middle and southern parts of Martinique, and we found the roads good for a Caribbean island.
