I just gave this feedback to Airbnb -- you can offer similar feedback here, https://www.airbnb.com/help/feedback
What I said:
"Airbnb is not matching us with the guests who are looking for what we offer. We've had to cancel 10 guests in a row because they did not read the description of the place and were not aware that we're offering premium lodging for chemically sensitive individuals, and they were not prepared to comply with our needs on their end (fragrance free etc.) On the flip, the guests who do (often direly) need us report they have not found us on airbnb, but through other, difficult-to-use-and-rely-on means, like word-of-mouth and Facebook groups. Up to 20 percent of travelers will choose a fragrance-free, eco- and chemically-conscious lodging as their first choice. This is a huge market segment. I am aware that many people have asked you to bring back your search terms feature as this was very helpful to people looking for chemically-sensitive and eco-conscious lodging. another option would be to add a check box for hosts , 'Chemically sensitive, eco-conscious' or the like which would allow the guest to only view properties that are suitable for them. "
Also, just FYI, we are preparing our home to be an EMF Sanctuary which will offer a low/safe EMF environment for the increasing numbers of us who are terribly EMF sensitive. Please let me know if you want to find out more information about our efforts in this regard. Love to all fellow lovers of Earth --
