I have ‘no visitors’ in my house rules. I then get my booking guests to confirm they have read the house rules and that they are happy with them.
This my wording in the message I ask them to agree to.
VERY IMPORTANT
Only registered guests included in the booking are permitted on or within the property - strictly no parties, unregistered guests, gatherings or events.
I had one couple last week withdraw their request to book - I knew they were looking to have lots of family over so it filtered that out before it became a problem.
I also let them know ‘I live just across the road’.
