@Nicole2094 I'm sorry you had a bad experience- the host doesn't sound so great, for sure, but then there are always 2 sides to every story. I'll give you the benefit of the doubt here that your version is a straight-up one.
You got refunded and you have the opportunity to write a review to warn future guests. Seems a little over-the-top vindictive to want to know exactly what penalties the host will receive. Getting a bad review is penalty in itself. But he'll probaby get some warnings, perhaps a suspension, who knows- Airbnb doesn't give out that sort of information due to privacy concerns. Fact is, guests can ignore a host's house rules, cause damages, be rude, and Airbnb doesn't censure them at all. I can assure you they are quite punitive towards hosts and not at all towards guests.
Did you read the reviews of this place before you booked it? What did they say? I assume you narrowed down the choices to places with good ratings and good reviews before giving a child the option to choose?
