The Castel du Mont Boisé can be found in southern France, at only 5 kilometers from the town of Montelimar. It is a beautiful old castle that was renovated as a hotel and restaurant. One can enjoy the food which is a mixture of provencal dishes with a traditional twist. There is also a pool, however this is not ideal for children because it is 2 meters deep, so you have to know how to swim or have constant parental supervision. As for the rooms, they cost around 120 euros per night, and they are very large, with private a bathroom and each one has special decoration, that you can see on the web site.They take reservations online and by phone. They were friendly and helped me to make my reservation online paying safely. The place is a little hard to find if you have no GPS.
