I respectfully disagree with your statement. We currently run three Airbnb's from our home and cleanliness is a major factor in attracting and retaining customers. You see, customers rate their experience at an Airbnb and the host also rates the customer. These ratings are then made public and future customers read them to decide if they should stay at the respective Airbnb. Our cleaning standards have always met or exceeded CDC recommendations even before the pandemic hit.
I’ve rented from and Airbnb and VBRO and have friends who have as well. My rental experiences have been fine, no major issue, though honestly I personally prefer and am more comfortable in hotels. One of my friends generally prefers Airbnb (big family), so the preferences of the diminished population of travelers will play a big role.
The challenge for you and your peers will be the percentage of potential customers who dismiss Airbnb, VBRO, and other sites as an option out of hand. If they never visit a site, they’ll never see a listing. Hotels will have the reverse issue, people who dismiss them out of hand and prefer Airbnb etc.
My guess (and that is all it is) will be that overall more people will stick with hotels over the near term, but it is only my guess. I wish you well, and good luck to you with your properties.
