I'm with my deaf friends, we were concern about communicating with Juan, but he did an excellent job to communicate with us by write down on paper also speak slow for us, he made sure we understand everything about Machu Picchu.
He was so caring to make sure of my mate who was struggling to walking on mountains, he support her to walking with him, so he can keep eye on her.
Hard work by walking for four days! But Juan helped us to make sure we keep going and didn't give up! We survived the Inca Trail ! To be honest I thought I wouldn't be able to make it!
