My last two independant last-minute bookings and subsequent cancellations claimed that they thought that both properties were located in the USA, when all my listing details (that I can see) are precise, & state that the properties are located in the Dominican Republic.
What triggered my doubts was that the guests claimed to not have passports, yet presented US driver's licences. One said that they would be arriving by a boat to Avalon. Another said a friend at works told them to. Neither reservation acknowledged the error, with my calender blocked until I called each guest personally by phone. Have contacted Airbnb support and am awaiting an answer as well.
