The lack of a basic profile from guests is a continuing problem for me as a host. I am surprised at how users have even a basic profile. On a few occasions, the name on the inquiry does not match the name of the profile. A person using a souces account, or a friend's account.
While many guests understand the protocol of verbally appealing to a host, others treat it as a hotel transaction.
Airbnb keeps a tally of how many inquiries a host declines. Regardless of the inquiry being less than informative. I've been told by Airbnb that accepting more reservations is my one "area for improvement. "
In my listing, I state "We appreciate guests with robust Airbnb profiles and give details about their reason to visit Southampton." But I'm not sure most guests read it.
