@Carolyn933 I very much doubt that 1 bad review would have removed his listing. There are things to consider though.
1. What did you actually rate him, was it a 1 star ?
2. Obviously what you have described is not acceptable, so maybe there was a health & safety issue ?
3. When you booked what was the listings rating ? This is probably the most important thing, as if the listing has had previous issues then yes, they will be suspended or banned.
4. How many reviews did the listing have, was it a new listing ? If they didn't have any reviews previously then yes, there is a possibility of being suspended.
It is possible that maybe the listing has been suspended for a while, but that normally happens after a few warnings about issues. I have known a few listings that have been suspended at least 10 times before they are fully banned.
Airbnb is really strict on their review system and believe me if a host gets a 4 star review, they get warned to improve ! So if a guest gets a few 3 stars or lower then yes, there is a possibility of being removed, but not just with one bad review.
