Sharing a house with other (unsafe?) guests

[Vita232]

I have a question.

I booked a room in the house that was not directly advertised as a non-host multiple-listings house. Having rented rooms in the host-occupied houses before, I didn't know it's possible to rent all the rooms in the house to different guests and live somewhere else. Based on the host's picture (with his son), it looked like I'm going to live with a family. There was no information or warning about other (multiple) guests. I ended up sharing a house with two young guys (I am a woman in my 30-s) – the fact I was casually informed about only after submitting the payment.

It could be OK (even though the place was somewhat dirty and badly-maintained), but one of the guests makes me feel very uncomfortable. It seems that he is not well psychologically. For example, he screams and throws things around in his room. This is just one example. There is more... When I expressed my concern to the host, he basically told me to mind my own business and my own stay – the wording he used was disturbing. 

I am now looking for a new place to stay and preparing to lose a handsome sum of money. I've read through AirBnb policies but it seems there is nothing about informing your guests about other guests in a house (are they men or women? are they safe?) or what to do when one of the guests is a psycho.

I would also see if Airbnb has an issue with his kind of listing. Many cities now have certain requirements for Airbnb's and Airbnb, as a company, has been trying to avoid bad press. Best example being shutting down "party houses." This listing maybe violating some kind of law Airbnb may want to avoid. In San Antonio, you are only allowed to rent 2 bedrooms max. Just thought I'd over a different take on the situation.
