My friend and I booked this tour on TripAdvisor. Pretty straight forward but due to COVID, instead of meeting at the McDonalds, we had to walk across the border and meet our tour guide there. We spent the day with Tadeo and he was great! He was fully of energy, very helpful, very friendly, and very knowledgeable. Very safe tour, very fun. We had a great group; it was a great time. Highly recommend this tour! If you can request for someone specific, Tadeo is the man!
