It was fanatastic , our tour guide was very knowledgeable on the history of the palace as well as the history of Mexico. Really enjoyed the day. Some tips or house keeping for future tours . Our guide did not have a Viator shirt on as described in the tour so we had to approach a few strangers at the meeting point before we found the correct person, would suggest an umbrella or sign if shirts are not available for staff.The meeting point was very large ,would suggest a more specific location be described. The tour of the palace required a very very steep walk, participants should be warned of possible issues with the climb. Also there was a long walk to the museum and then a the tour of the museum. Participants should be aware of the distance and length of this tour. I cant stress enough how fantastic the tour was, I guess we were not prepared for the length and the amount of walking. Finally we requested an English tour guide,and Sergios was great however we had a person that spoke no English join the tour which meant Sergio had to explain everything twice. Would highly recommend Sergio and this tour!
