This hotel has an excellent location, with a private beach, right on Point du Bout, within very short walking distance to the marine and the set of shops and restaurants, as well as a few beautiful beaches (and a little longer walk to one of the few casinos on the island, if one is interested in that). It has kayaks, jet skis and windsurfing boards to load - but the weather when we were there prohibited use of them. It has a windsurfing school - which was fully booked when we were there (they gave the lessons at a different beach due to weather). It has a spa, which we did not use. It also has tours and boat trips (in French), which did not use since they were fully booked when we arrived. Therefore, it is important to plan ahead.
However, I don't know why this hotel is rated as three stars by the local government. It lacks basic amenities such as a mini-fridge or a restaurant that allows one to order food - the restaurant there is only buffet for all meals. There is no ice machine - one has to ask the staff at the bar or restaurant for that. There is no convenience store in the hotel, but there is a small one next to the marine (with limited hours). The rooms are clean but basic - they only have showers, not baths, for example. The breakfast buffet was nice, but not really impressive. Use of spa amenities (such as hot tub) is extra cost. The pools are smaller than they appear on the web site.
Overall, it was ok, but from a three-star hotel I would expect more.
