Below are reviews of the city of Huatulco, Mexico from an actual visitor's perspective.
Beautiful!
The City of Huatulco is beautiful and so easy to get around. We walked everywhere and were able to get everything we were looking for. So many cute little shops. There is so much to do and see if you want to go on an excursion. Very affordable as well! It is a 5 minute walk to get your tickets. Not commercialized. A true Mexican experience!!
The city looks clean and it's super safe. You can walk through the city and buy nice food and handcrafts. The airport is about 20~30 mins away from the city and hotels.
