A guest has booked for Champion's League weekend; he has booked my place on behalf of 3 couples, he has no previous reviews to judge him by.
He started sending multiple insistent inquiries on what's app as to whether I would allow an extra 2 couples to stay. The messages were a little pushy and erratic, sending just a few words at a time and they were also sent from his partner/girlfriend/wife, who subsequently does most of the messaging. I replied saying that it was my home and I felt uneasy about extra guests, especially as it could turn raucous. They agreed they would not allow extra people to stay.
After everyone warning me that they'd probably shoe-horn the extra guests into the property anyway without my knowing, I emailed the guest a couple of weeks later. Within this email I said that given the booking crisis for Champion's League, I would be happy for them to stay if they were willing to pay an extra £150 per night (as compensation to me for possible wear and tear to the property). They failed to respond at all. A month later, I emailed to say that their original messaging and their lack of response to my last message had left me nervous and I wished to cancel. They responded immediately to beg me not to.
What would you do? If I cancel I loose my superhost status and ability to rent out the property again. Is it worth it for peace of mind or am I being too nervy?
