@Cassandra182,
If you find a safety hazard in your rental you are required to notify the host right away, and give the host an opportunity to remedy the problem. You should always communicate with the host via Airbnb's message system so it can be reviewed by Airbnb, if necessary. If the host is causing you to have concern for your safety, leave the space immediately, and/or call the authorities. Once you are safe, you can contact Airbnb to report the situation. I also recommend purchasing travel insurance whenever you staying away from home.
