Good @Maureen242 - it hasn't occurred to him to leave a retaliatory review. Cross your fingers and hope he doesn't.
I'd leave off reviewing him altogether or leave til the last possible moment before the 14 days are up, so he is not prompted to leave one of his own.
If he DOES leave a reivew adn it turms out to be nasty, be sure you leave a factual unemotive professional response ( bear in mind this is for the viewing of future guests) You can come here for advice about phrasing etc
