@Vicky353 Yes, all reviews are published. If only one party writes a review, it will appear after 14 days, if both leave a review, they will both be published soon after they are both submitted.
Please, please, leave honest reviews for your guests. It is not a matter of being the "bigger person". When you fail to warn other hosts of bad guest behavior, you lead other hosts to assume this will be a good guest, accept the booking and then get hit with the same nastiness you got hit with. Bad guests need to receive the bad reviews they have earned by their behavior, so eventually they will be banned from the platform, rather than passed around from one unsuspecting host to the next, who either fails to leave a review or leaves a fluffy, misleading one.
FYI while guests can read the review you leave for them after it's published, they can never see the star ratings you left for them, so if they deserve a 1* for whatever, dish it out.
It helps to think of reviews as neither "good" nor "bad". Think of them as honest. Keep in mind that you aren't reviewing them as a person, you are reviewing them as to their suitability as a guest.
