My wife and I had originally had the classic 4D/3N hike booked with them, but my wife unexpectedly got ill a few days prior while were in Cusco... so instead we came to Machu Picchu by car-->train. Abraham met us right when we got of the train at Machu Picchu town. Super, super nice guy. We first went and had a nice breakfast at a quaint spot in the town, and we talked about what the full trek would have been like had we done it -- and we all agreed that with my wife's illness, it was a good idea for us to have changed out plans to the day trip only.
Abraham was super knowledgeable about history, about Machu Picchu yes, but also about similar world history -- being a history buff, particularly about ancient civilizations myself, we had great, stimulating conversation. After that we three took the bus up to the MP archeological site. There we proceeded on a 2 hour walking tour of Circuit 3. Abraham was again super knowledgeable, and pointed out amazing details everywhere we went. We then of course hiked to the top to get the classic "postcard pictures".
All in all we liked Abraham a lot, and when (not if) we come back to do the full 4D/3N trek, we'll definitely do it with Abraham and Life Expeditions. Thank you Abraham!
