Great topic
When I went through the processes of listing my place accessibility was high on the agenda for others needs.
Alas when one looks through some of the listings claiming to be accessible for wheelchairs many simply have not taken a Tape measure to measure the very entrances to ones home.
At a guess there's probably 50% of listings that would not even qualify and could be interpreted as been misleading those with disabilities
Airbnb must inform and advise Hosts to check there Listings as the basic door way entry to a persons home is generally a lot smaller than 32inches.
There's also other factors like a step into the shower, hand rails etc also to take into account.
Having worked at the coalface of a 5 star hotel in my younger years helped me decide what to include.
There's also factors like the floor surface, e.g does it get particularly slippery when wet, marble does and is incredibly dangerous.
Outdoor areas where there may be bluestone pavers etc are also a risk to those who may be different enabled and have pre existing challenges..
Thanks for bringing this to the fore & thanks Lynda from in Kaikoura a fellow
