Kara,
I had a dangerous experience with this several weeks ago and took my space down until yesterday to tighten it up.
My biggest mistake was letting them in the space. They booked for one and showed up with 4 at 4AM, hours after when they were supposed to arrive.
I felt just let them in the space to not cause a scene in those early hours and disturb the neighbors. I should not have done that. They smoked pot in the space and stunk up the entire house and then would not leave at checkout and stayed 3 hours past check out time. It took me driving them to just get them off the property.
My co-host was watching this on our outdoor and host space cameras and called the police as she was fearing for my safety since there were 4 of them and one of me. They actually entered the host space where we have a security camera and were poking around my garage. Quite a mess. Had I not let them in, called Airbnb and the police if necessary it would have not been as big an issue. I also made several other mistakes in my listing that allowed this to happen. If I was one of my neighbors I would not have been happy with me allowing this to happen.
After the fact, Airbnb was totally useless and could have not shown any less concern about this had they tried. Totally useless customer service from 3 different reps. They showed no empathy and just wanted me off the phone as quickly as possible.
To help prevent this in the future I added a $250 security deposit and only Guest who are ID verified and have recommendations from other host are allowed to Instant book. I also have this in my listing in about 3 places and it is a question they must respond to at booking. I also then message them right after the booking telling them I am just quadruple checking that they are aware of the 2 guest limit, even during the day, and that they will not be allowed to stay if they show up with more guest than that and Airbnb will be called to arrange other arrangements for them. I keep sending them this message every couple hours until they respond to it.
I am going to stick with Instant book for now but one more issue and it is going off. Then all guest can request and will need to answer the question before I will approve their reservation. Guest that do not meet the requirement already have to request to book due to my settings and cannot instant book.
So to summarize my mistakes were:
1. Allowing anyone to book with instant book. At the very least require ID approved. I would highly recommend recommendations from other guests also.
2. No security deposit. Put a security deposit of at least $150. I did $250. This helps make people think twice about breaking the rules.
3. Letting them enter the space. This was my biggest mistake. Give em an inch they take a mile. So true.
4. Use Airbnb's self-serving auto pricing. It dropped my listing to $54 and I did not catch it. The result was a group of young partying adults to be able to book my space. Airbnb's auto pricing is geared towards renting your space at all cost. Airbnb still make out (they don't have to deal with anything) while us host seldom do.
In the end, this was entirely my fault as I was not diligent in my listing. I hope this helps others from repeating my mistakes 🙂
