The Let's Go series of travel books are written by Harvard Students
who have visited and stayed in the country they write about. The book
is really great for the student traveller; they highlight the cheap places
where you can buy souvenirs, eat, is very informative. Highly recommended.
I used Let's Go Spain and Portugal on my trip to Spain. [check out my Spain gallery]
This is the 1999 edition of the book. It is updated every year. Highly recommended!
