@Justin-And-Sarah0 welcome to ABB CC
When advertising one's property for rent, especially if it's an entire home and there's obviously more than one person coming to stay, you are within your rights to message back and ask for the names and details of those people so you know who will be on your property.
It's important to keep channels of communication open and sometimes people take a wee while to reply for whatever reason, maybe they lead busy lives, have a full on lifestyle etc, it's not to say they are avoiding answering questions.
Maybe ask a few more questions of them, and future guests.
Keep an eye on your property and remember to disclose any security cameras etc you may have to protect it.
Keep a watch from time to time on it when your home is rented out for Peace of Mind.
There's much helpful info here in CC if you use related keywords in the searchbox
All the best
