@Tracie24 this is a third-party booking and it is not allowed by Airbnb. Aside from the obvious issue of them not being able to communicate with you, this brings a score of others. You will not be covered by host guarantee (not that the program is worth very much but still), technically Airbnb might not even pay you for the stay. If something happens to your property, there’s nobody to hold responsible. This is just the beginning of a big list. For starters, these parents need to be added to the reservation through the platform. This is the main problem I see with the situation right now.
Beyond that, how much communicating do you usually do with your guess? I feel like most of mine come and go with just a few words exchanged.
