@Lia63 Getting to know my guests before they arrive is what I like to focus on in my messages. I start with understanding what brings them to my area and the names of all the people in the party. I confirm that they understand a few key components of the listing, such as it is a private room in a house that is share with me and my dog. Later, I confirm the arrival time so I can meet and greet them. I offer to help with reommendations about dining or events in my area.
Your profile could have more information about you as a person and a host. Shared space is very personal and you can enjoy that personal contact if you like. Good luck in your new business.
