Carlos was there waiting for us right on time for our trip. We had already visited the more popular sites on previous days, so our expectations were high. Carlos' knowledge of Pre-Colombian history and artifacts is thorough and he presented the facts and observations with scholarly clarity and objectivity. We had also requested trips to a few UNESCO WHS monasteries. He was happy to take us there and provided great insight. Our trip ran over time and Carlos remained patient and polite.
