You are definitely not the only one! I only know to try to "kill the customer with kindness" and be really kind in how you say anything, even telling someone you have to evict them, and be willing to say you're sorry - not that you DID anything wrong, but you're sorry they have the circumstance, or you're sorry their experience was not what they expected or...
But that said, people can still be wicked with reviews. We have a beautiful apartment community with the nicest and most professional team. A resident's dog bit a neighbor badly and the resident wasn't willing to give up the dog so we asked him to move. In less than 2 weeks our google rating went from a 4.6 to in the mid 3s. People who don't live there, made up people, people we could prove had never lived there wrote scads of made up negative stories, some related to how un-pet-friendly we were, but other things too, like maintenance issues or feces or bugs or mean staff. We have written google with proof the reviews are not residents or former residents, and we await their final "ruling" on removing the reviews. And they keep coming. More every day. We respond to everyone, including a kind way of saying we have no record of your having lived here...Will let you know the outcome!
I still say, you'll always have the "mean people," but to your best ability, be kind, be respectful, be honest and firm, and usually it will go better!
