@KayKay0 Yes, I've read posts here before where the exact same thing happened. Employee guests arriving not being made aware that it was a non-smoking listing, etc, etc.
If you get employers booking for employees in the future, I'd first check with Airbnb that they actually have a business account, because otherwise it's a 3rd party booking that is not allowed. If it is a business account, I'd let Airbnb know about your problems in the past with this kind of thing and ask them to please contact the booker to make it clear that they must refer all their booked employees to the listing and that they must acknowledge that they've read it. I'd be really firm about this in a message to the booker yourself, as well. Let them know that you've had bad scenarios over this before and that you'd prefer not to accept the booking unless they can assure you that the employees will be made aware of the amenities, house rules, etc and comply with them.
I'd leave a response to the review, something like-"The complaints in this review are a direct result of an employer's failure to convey the listing details and house rules to the employees he booked for."
