To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Overall, it is a decent guide book. It was the most recently updated of all those out. I took off a star because the index is poorly organized and there is no mention of Chalcatzingo, an amazing Olmec site in the Valley of Morelos. While this area has little to no tourism, the locals seem to be trying to attract more people to this beautiful area. Indeed, Morelos (the state of) gets only a small paragraph in the book at all. Xochimilco is not in the index by itself - you have to look at the entry for Mexico City. The entry on Xochimilco has incorrect and misleading advice (you don't buy food and drinks before boarding but rather you signal to the floating vendors when you want something and they bring it to you). No guidebook is perfect but a better index would be really helpful.
Detailed guide from an experienced hand . Bought it because we like to have a physical book . The format is still traditional with extensive listings and perhaps not quite evolved for a modern traveller with access to internet information as well .
I have just discovered that the basilica of Our Lady of Guadaloupe in Mexico City, which is visited by over 1.5 million pilgrims annually is described in the very thorough coverage of Mexico city. I need to apologise for a previous review in which I claimed it was omitted. This a truly excellent guide. Amazing value for money!
