We have used Airbnb across multiple continents, and Arturo and Marie's place in San Ignacio is the absolute best experience we've ever had. Not only is your room massive, but breakfast in the morning is a straight up feast. They are ideal airbnb hosts - sweet, helpful and accommodating. We mentioned that we would like to visit Tikal, Guatemala, and Arturo personally drove us to the border and across customs, and linked us up with one of his friends who took us there for the day. They are lovely, gracious hosts, and you should absolutely stay with them if you visit San Ignacio.
