We used this guide book during our 10 day holiday in the Algarve. We hired a car for 3 days and the information in the book helped to plan our adventures and get about. It has brief but informative section on different places to visit in the region and also info. on places to eat/ things to see/ etc. We didn't use it for accommodation, so I couldn't comment on how helpful it is for finding places to stay, but the places they suggested for food were often really good. I would definitely recommend this book to anyone visiting the Algarve.
