We had the luck and the pleasure to stay here on our Holbox adventure. You get the whole place, the building on the right is a little kitchen area with a full bath, dining table, and great patio with two hammocks, and the other is the large master bedroom with full bath, a couple sitting areas and a hammock as well. It's right on the lagoon(lots of wildlife) and off the main roads(quiet and secluded) but a short(5 min) bike ride into town center or beach. Bikes provided.
Willy and Martha were super gracious in assisting with transfers and area restaurant suggestions.
Highly recommend staying here if you don't like the huddle and bustle of staying on the main drag, but can get there inside of 5 minutes.
