@Sara1585 I don't use IB, so all guest have to send a booking request. When they do, I send a message, and after thanking them for their request and before clicking on Accept, I'll list the things I feel are important for guests to be aware of in case they haven't thoroughly read through the listing description.
So in my case, it's "Hi XX, thanks for choosing my listing and sending a request. I'll be pleased to host you, I just like to make sure guests are aware of the following, which is mentioned in my description:
20 minute walk from my home to town and the beach.
I have a large friendly dog who occasionally barks.
Guest space is for one guest only.
I've been lucky in that almost all my guests seem to be through readers and good communicators, so they usually reply quite quickly, saying yes, they are aware of all that, that they like to walk, are dog lovers, are travelling alone and looking forward to staying here and meeting me.
It's not yet happened that they haven't answered before I have to either Accept or Decline- if they didn't reply in time, as long as their reviews and profile looked good, I'd likely Accept, along with another message saying I was accepting the booking, on the assumption that they had read my previous message and had just been too busy to answer yet.
