I agree with the other reviewer - I too had access to a few different guides on my recent trip to Rome and wasn't even sure if I would take the Blue Guide as it looked a little uninpiring with just tons and tons of text - I admit to liking a book with a few nice pictures and easy to use lists of things to see etc. However, this ended up being the book I used most. Rome is such a fascinating place with so much history and meaning and frankly, the other books were pretty useless apart from giving you something to flick through and see what you may be interested in doing (apart from the Eyewitness guide which gives a map of the Sistine Chapel roof- clearly explaining each of the pictures - well worth having). Once you get to any given place, the other books had little or no information or depth but the Blue Guide was absolutely packed with details and explanations. I can safely say that had I not had this guide with me, I would have missed half of what I saw! It is particulaly essential in the Vatican Museum, and guides you through it room by room to make sure you don't miss anything. With this book, you really don't need the headphones at some extortionate price after you've just paid the entrance fee! Highly recommended to anyone wanting to know a bit more about what they are looking at apart from the fact that it's all so beautiful.
