Casa Suzana is located in what is often called the "Corpus Christi" neighborhood of San Miguel de Cozumel.
The official name of the neighborhood is actually "Andrés Quintana Roo" but nearly everyone refers to it by the name of the parish for the Corpus Christi church. It used to be, and often still is, called "Gonzalo Guerrero" so there are 3 names you may see used for the neighborhood.
Google Maps incorrectly calls the neighborhood Gonzalo Guerrero, and Garmin incorrectly places Casa Suzana in Colonos Cuzamil.
