it MAY be a phishing email which leads you to the website which looks like Airbnb but it is not. So when you log in to this website they get your username, email, and password and can change your bank account and everything.
Login to htpps://www.airbnb.com on your laptop, check if there is a green padlock on the beginning of URL /address, log in and change your password. Don't forget to check your bank account details, phone etc... If you can't login then contact Airbnb immediately and report it.
