I used this guide when driving around this area of France this summer and found that not only did it provide accurate factual information, but that it also captured the atmosphere of the area. It covers individual towns and villages in sufficient detail that you do not need to get individual guides, and the coverage ranges from describing the architectural features of a building to where you can go white water rafting. I went to several of the hotels and restaurants mentioned in the guide and these had been accurately described and the prices in the guide were up-to-date.
The guide has a very helpful section on local food and wine, so that you can understand exactly what the regional specialities are before you order them.
I do however have one criticism: I did not find the maps of the city centres easy to follow.
If you are driving around this area, the green Michelin guide is also very informative and suggests lots of good routes along country roads.
