I’m also a woman sharing an apartment with women only guests (spare bedroom). If in doubt, I always ask guests to confirm their gender (I don’t ask if they are born man or woman as such). I’ve recently had to turn two men guests who had not noticed the obvious which is that the bedroom is only offered to women (in the title, in the description, in house rules and just about everywhere). Today, I’ve had a request from someone foreign with initial in another language, but enquiry in English. That guest shows with good reviews in translated English, with those reviews always referring to the guest as a guest, never as a ‘he’ or a ‘she’, which is a problem. I’ve messaged the guest to ask about their gender and if I don’t have an answer within the 24 hours timeframe for me to potentially accept the booking, I will have no hesitations but to decline this guest, because I consider that a lack of reply is a lack of respect, suspicious and especially unsafe.
Hope this helps.
