Negative reviews are not easy I know I like everyone have had my share.
I am also a wheelchair person so maybe a different perspective,
Your bedroom pictures show beautiful big windows both with curtains, if one window had a curtain removed that put you in a bad position. From a Guests point of view, that is an opening that could be viewable in a bedroom space that expectation is privacy. Yes, it is on the second floor and your neighborhood is not full of peeping toms with binoculars. The Guest is spending 3 days someplace unfamiliar to her, in that situation would you feel comfortable or checking window often.
As to your bathroom set up. In your listing you say chair is available. The pictures show the tub with and without the chair. No mention that removing the chair is Guests responsibility. Just as yes it is irresponsible for her to assume your wheelchair usage is related to your cleanliness is unfair. Assuming she can safely remove a bath chair because she is not in a wheelchair is unfair, She could have arm or back disabilities you don't know.
Again looking at your tub picture with the chair, it is a larger shower chair. Shower chairs are not inexpensive and that is nerve wracking to some people, what if it breaks.
I am sorry but your picture shows a glass wall and the chair positioned right along the glass, I don't see an easy way to get in front of the chair and shower.
I do agree though you should request Airbnb remove the review. Just on the fact that she associated uncleanliness because your wheelchair bound. That is a derogatory remark, your wheelchair has nothing to do with cleanliness or lack of cleanliness. Stick to that one remark. Airbnb can not determine if she is lying or are you lying. Her statement about your wheelchair causing you to be dirty is judgmental that disabled people can not take care of themselves. That is a discriminatory remark.
