@Tracey16,
Hi Tracey, sorry to hear you had a bad experience, no doubt it was also a learning curve for the parents who have discovered that it may be better if they choose different accommodation in future untill their children are more settled in their behaviour
When creating my listing, I remember Airbnb advised not to have items in guest areas which I would be very distresed about if damage occurred, so I knew to move the family heirlooms. But not everything can be removed.... This is where we need good matches with guests and it's still ok to be an adult only venue. That can help a bit.
Regarding home insurance, it's for residential use by homeowners and residents. If you are using part of your home for commercial purposes, then you may need to upgrade your policy.
It's easier just to screen your guests, and review what property and spaces are available. Reading your story and another about burnt benches, reminds me of why I don't have kitchen areas available and the tellies are $200 dollar models.
Sorry about the expensive learning curve. It hurts.
Sincere regards, Christine.
