Technically, per Airbnb's Non-Discrimination Policies, Hosts are not permitted to deny bookings based on age alone unless there are age restrictions imposed by an HOA for example, or by Building regulations etc.:
Non Discrimination Policies
https://www.airbnb.com/help/article/2867
Airbnb hosts may not:
- Decide for guests that a listing does not meet the needs of guests of a certain age or guests with children or infants.
- Impose different terms or conditions or decline a reservation because of a guest’s age or familial status, unless such restriction is required by applicable law or regulations.
- This includes imposing rules like “no guests under 21,” charging more fees for guests of a certain age, or discouraging certain types of guest bookings because of age or familial status.
Unless you are in an HOA that has an age restriction of some sort, not sure you can restrict bookings based on age. Other Hosts do this, but technically it violates Airbnb policies unless you fit the exemption criteria (other platforms do allow an age limitation for bookings).
That said, you are permitted to decline any reservation as a Host, but not sure I would say anything about age. What kind of reviews did this person have? Did you ask any questions about why they were coming? Visit relatives? Vacation? Who will be in the group? You can also require that all guests create an Airbnb profile and then the booker needs to add their names to the reservation.
Declining a reservation won't affect the listing rank as long as you don't do it "alot" according to Airbnb. Who knows what "alot" means?
