Rented the place for a friend that needed a place to stay for the night. The hosts where very polite. The booking allows for two “guests” and I only selected one. I was refused to visit my friend on the premises even though I had no intention of crashing there. Rather than tell your guests that visitors are not allowed according to the rules of Airbnb maybe just admit it’s you that don’t want people to have visitors, as is your right. Maybe make it part of your ground rules so people know before booking.
