Hi @Ann35969,
Welcome to the Airbnb Community Center and thank you for posting your query. We understand that many Hosts may have the same question.
Hence, as a reminder to the Community, Hosts can note in their listing description any applicable restrictions that are set by law, regulations, or their housing community (e.g., senior housing), but cannot set their own age restrictions or add terms or decline reservations based on age.
You can also have a look at a summary of our nondiscrimination policy for more information.
I hope this helps!
