We took two one day tours by Estigo from Mexico City. They were very accommodating of our wishes to design our own tour and were very professional, reliable and informative. Especially exceptional was the private tour they put together of Temple Mayor after hours. Run by an archeologist from the site it was extremely interesting. Estigo was accommodating to our wishes to have long full days and all went smoothly.
The guides were great and especially thankful to Gonzalo for all his help in arranging it, and especially helping us with our hotel problems (which had nothing to do with Estigo, but he went above and beyond to try to solve our problem). Highly recommend this tour company.
