@April184 Hi well, looks like you have a few things to learn about hosting.....there's loads of places to read up especially on airbnb website....... youtube.............FB and all over the web.
My big question for you - Why would a person book a place for 10 people that cost $200 a night for ONE PERSON- they would NOT do it..............it is up to you to turn off IB so you can vet your guest and find out "What brings you here?" ask questions and find out and that way you can help avoid such awful guests like you just had. Sorry about that! Make sure and be honest with the review - they were not good guests. If you haven't written on your listing that you will charge for late check out you can not do it. Plus, the guests will have to approve any request for more monies --- good luck collecting that. Folks like these you had need to be stopped and make sure you give them 1 - 2 stars - thumbs down and
I would write -
The guest arrived with 4 extra unregistered guests......
there were multiple things damaged in the property that have to be replaced. Also, much extra deep cleaning had to be done after their late exit. This guest is NOT welcome back.
Let us know what you do with filing a claim or review.....don't let these folks get by with a good review BECAUSE we all will suffer and it tells them they can get away with such.
I would file a claim for the damages.
Good luck, Clara
