@Jayme23 Most of the guests I've had have sent very informative, personable messages along with the booking request, so I haven't had to ask many questions to set my mind at ease about them.
If they just write something like "Arriving around noon" or "Looking forward to.coming", I use the things that are crucial for my guests to know, that are mentioned my listing description, to get a sense of whether they have actually read it.
So in my case, it's "Hi XX, thanks for the request. I just want to make sure you've read through the listing info and are aware that it's a 20 minute walk to town and the beach and that I have a dog and a cat ( in case you have allergies)".
That usually prompts a more informative message. As I only host one guest at a time in my private room listing, and I live here, so no one can sneak in extra guests or pets, etc, I don't need to confirm guest counts and things that hosts with entire home listings do.
And if I want to know why they show as members for several years, but have no reviews, I"ll just be straightforward- "I'm kind of curious as to the fact that you have no reviews, but it shows you've had an account since 2017. Did you just never book anything before?"
