It is a mainly a phishing attack, but not CSRF attack as far as I know. The url is not with the domain airbnb.com or withairbnb.com (both are the official domains of airbnb), so my browser will not send my host account cookie to them. That should be fine.
I have reported this message to Airbnb already. But you are right, in general, one should not click any link because of CSRF (although I am sure airbnb engineers should have the CSRF token or samesite flag setup correctly to mitigate that).
