"And it doesn’t take rocket science to know you don’t put a strange man in a house with a woman…. "
Im saying this in a neutral tone and it isn't personal. I gotta be honest, I deplore women who act like this about men. The whole "strange man" argument has been brought up at my place several times by women who didn't bother reading our ad and then were surprised that men are in other bedrooms and wanted a refund contrary to policy. And ya'll never nice about it. One woman went as far as to book a month, found out other men stayed on site(three other women also by the way), and left demanding a refund. When I refused to do more than refund if we rebook (which as it turns out would have been about a 95% refund) she left me a bad review and refused to take it down so I rescinded my offer. I just kept her money for the month long booking for being an asshole about it.
Its very combative and strewn with passive aggressive comments just like the above one I quoted. Your hangups with men, are your problem to deal with. Not ours as as host. I have had SIGNIFICANTLY more women who don't have this problem stay with us than do. Probably because the ones with hang-ups book a place that suits their needs. They dont book a place that is coed and then complain about "strange men" like youre doing here.
If you are that frightful of men existing, then stop booking shared places unless they advertise women only for the entire property. That's the ONLY valid thing for you to do. Expecting that because you are a woman there won't be men around is ridiculous.
All that said, if your host advertised the amenity that says words to the effect of "bedroom door has lock on it" OR if they verbalized it in the ad someplace then you can 100% use that to get out of your reservation if they wont add a lock right away.
If you do not see that in the ad, then there is no reason you should expect it. To look you wanna check out the list of amenities as it should be listed there. I can snap a pic of what it looks like on my ad if you want to know what it looks like.
