This is the book my wife and I always (and still) carry around with us when strolling in Paris (discreetly tucked into an overcoat pocket, of course). I think the best way to use it is to skim it repeatedly before going, and hi-liting or placing post-its on places that sound worth visiting. Then, once at the given locale, Access tells you what else is interesting in that neighborhood.
I've heard criticisms of this book to the effect that it doesn't categorize restaurants, hotels, and the like. It isn't that type of guide. What it does best is truly point out the best of each neighborhood, and provide historical background as well.
One other note: previous editions have far better maps than the newest edition. I beg Access to return to the beautiful detailed maps and abandon the more generic maps in the current edition.
