Hello @Zvi1
Great advice from @Shelley159 and I remember when I first started out on Airbnb I got a few of these similar requests Always said no and realised soon enough that it was a way for them to go off platform - no Airbnb fees but no chance of Airbnb stepping in if I had a problem. The only one who would have benefited would have been them.
All the best with your hosting
