'In this business … it's all about Getting Booked!'
by Elena Badia, The Hosting Journey
If I were you, I would leave the decision to my sister to handle the place and encourage her to be a co-host, read well Airbnb terms and policy and motivate the listing.
As a new host, it's always hard to decide, in fact, to boosting the listing by choosing to offer the 20% discount to the first three guests and turn on the instant booking. Most of the hosts wouldn't wish to prevent the party guests and circumstances happen.
Since the host stay nearby, to take control of the instant booking of an entire home in need,
- Set a pre-booking instantly bookings message, ask them for the journey reason, who shows up, and other questions
- House rules with 'no parties' and the noise fine.
- Deter a guest in the listing description. You use noise-aware systems.
- Meet the guest during check-in, pass the key and well communicate and screen the guest again
- Reminds the guest that is an outside camera installed
