I just had a quick look at your listing .... you've ticked loads of "Accessibility" features .... to me, that suggests that you are set up for and welcome disabled guests .... and as it's a room in a house, I guess they just expect that little bit more, or they expect that you're FULLY accessible with everything, so don't need to bring an assistant .... (I haven't read the full descriptions or looked at all photos)
Even if some of our properties have some accessible features, none of them are deliberately designed as "accessible" for disabled people .... I tend not to tick the boxes .... maybe show they're ok for older people, but certainly not for all disabled people .... I don't want to put people at risk, nor put myself or my business at risk ....
We all re-think our listings based on experience .... maybe you need additional information saying what you will and will not do, exactly how accessible your property is etc etc? Maybe you should say to bring an assistant if required? You'll know best about this!
