Great location walkable to town (big hill on the way back, but you have to work off the fryjacks somehow!) directly across the street from the (wonderful! visit it!) Iguana sanctuary at the San Ignacio Hotel. Clean, quiet, private, with plenty of parking and help from the very kind onsite manager if you need it. There were people next door, and we saw them but never heard them.
We did two tours with Cayo Inland Expeditions (ATM and Xunatunich) and both were great, super convenient to be picked up/dropped at the house and the owner offered a discount for booking this Airbnb.
This place is primarily two large bedrooms/bathrooms with a small office (with door and sofa bed), kitchenette, and living area. There's not a lot of communal space to hang out indoors. One note to consider: the bathrooms do not have separate doors; they are a part of/within the bedrooms, so we had a little negotiating for use between our two teenagers. In the end, they worked it out. All in all, we recommend it.
