Frankly this is the worst travel guide we have ever used. Some of the Michelin Guides (we have used others including those for Brittany and the Dordogne) are fairly useful but this one falls a long way short of that. The book is set out in alphabetical order: as one other review says, this is a book covering a very large area and so it would be much more useful if it was split into smaller areas (as the Dordogne guide is, for example). The index is cumbersome, cross referencing within the book is extremely hard to follow, and some of the maps are pretty useless. All of this made the book extremely difficult to use.
The rating system is patchy. Some extremely worthwhile day trips we made only had a passing mention in the book, with no stars. Other items which were given 3 stars were disappointing. By way of example, some religious sites were worth visiting but did not seem to us to merit the full 3 star status and 4 or 5 page description which was given in the book. As the other review says, this book really needs to have a fuller and more objective approach to be worth using.
I would recommend avoiding this book if at all possible.
