I do get occasional request to view, though it's most prevalent with one category.
Airbnb has become quite popular with the Photo / Film industry in the UK.
Airbnb listings are considerably cheaper than Location Libraries.
So those wanting to shoot invariably request to view, which is understandable.
However, I've adopted a special policy in response.
I charge for the viewing which must be done as a normal booking: 'Special Offer' c. £ 30 or 40 depending on their project budget.
I stipulate if the shoot goes ahead then the viewing charge will be deducted from the overall negotiated price.
It's proved perfectly acceptable to these people.
The benefit aside payment for my time for the viewing, is that the booking as per norm includes the exchange of contact details.
In turn i've adopted this policy for the very occasional request to view by normal type of guest.
To date no one has been willing to pay it, and I don't recall anyone actually booking.
However, I'm generally not nervous about the idea that an Airbnb guest might wish to view because I'm not exclusively an Airbnb host. I also rent longer term on the most popular site in the UK, SPARE ROOM.
It's normal for people to request viewing.

Consequently, I would avise that if in principle you feel comfortable with this prospective guest to view, then you suggest to him that he do a minimal booking via Special Offer, and he should arrive with his Passport or ID which you can photocopy.
