Last time I checked, I did not lug a guide book around a city for its hotel listing. If I want a list of hotels, I will go get one and usually they are all irritating for some reason or another. But generally I know where I am staying before I get there.
I agree with other critics that it would be nicer if Paris is broken up by Arondissment, but at the end of the day, it doesn't matter. What I love about these guides (and I have them for 7 or 8 cities now) is that they are visual. And I am visual. When I have a half a day in a city (which I frequently do in London or Paris for business trips) I can grab the guide and see what is going on in my little corner. I learn quickly what things are nearby or far away. And what I can realistically get to.
But the maps, the sense of spatial distance, the breakdown of what is worth seeing in an area and a bit of history are the best.
So if you need to know how to play with Euros or trains or hotels, nope, this guide isn't going to do it. But if you want to use it as a sightseeing guide and want to know what is where, and the best things to see in whatever area you are in, then this is the book for you. If you already know your way around the basic European systems and want to know what to SEE, then this guide will do it.
