Hello @Terri416
Unfortunately you will get some guests that are completely unreasonable. I've only had one in six years of hosting.
What sort of vetting questions do you ask your guests to ensure they are a good fit.
What issues did the guest complain of that weren't amenities mentioned in your listing.
The message you get from Airbnb is automatically sent when your ratings drop below a certain level. Try not to take it personally.
There is an awful host near where I live (actually a management company) she consistently gets 4 to 4.2% ratings on Airbnb and terrible reviews. Yet Airbnb do nothing and she continues to host.
