I actually skimmed most of it, and my BFF threatened to test me (eep!).
My main reason for picking it up was to be reminded of interesting places I'd seen, and to find others for an upcoming city break. I found both, so yay! I actually found the maps included in the guide more useful than the fold-out one I had purchased specially (larger street names).
So it's a decent travel guide, I guess. Though my patience with most non-fiction books is not the best, so perhaps you should also look for other reviews.
