I agree totally with the reviewer who complains about the lack of relationship between map numbers and street addresses. This edition is completely messed up, and unaware tourists are going to be standing in Florence, book in hand, wondering where the #$@&! the museum/gelateria/hotel is that was on the map for that location. What a shame - Access guides are usually just the best street-by-street guides around. And this isn't a matter of just being one number off, consistently, or of the location being just around the corner. Numbers on the map send you all the way across town sometimes, compared to where the location really is. Extremely weird and unexplainable. Why isn't HarperCollins pulling this off the shelves and/or offering buyers a corrected edition? Someone really dropped the ball here.
