My friend who has the book moved away so I can't look at it. You can expect lodging at a B&B in small villages to run 25-40 euros a night. If you eat in restaurants for dinner, plan on 12-18 euros which will get you a pasta dish and a couple of drinks, more if you want meat dishes. I recomend carrying lunch with you. Bread and some cold-cuts at a grocery store will run you about 4-7 euros a day. If you want something other than water to drink, just bring powdered drink mix with you. That stuff is expensive over here. Same with things like power bars.
