@Joan243 Ali, above, has a point. I also looked at your profile and you are obviously a new airbnb member, which is fine, but many hosts are reluctant to accept bookings from new guests with no reviews and no info.
The hosts may indeed be discriminating because of the disabled issue, but it could also be because of the lack of info on your profile. Try writing something up, mentioning your daughter, what is required in terms of access, as not everyone in a wheelchair has the same access needs, as well as some other info about yourself and your daughter and see in the future if you get a different sort of response from hosts.
And I'm very sorry this has happened to you.
