@Enrique31 Were there any charges made to your payment method? If so, contact your bank right away and tell them the charge was unauthorized.
Also, check all your account settings for email, notifications, credit card info. Be sure to check the login alert under Security. Then change your Airbnb password. In the event your email account was compromised, change the password for that as well.
Hopefully that will stop any unauthorized use, but it you see continued login ins from strange places / devices, best to contact Airbnb.
