He must be one out of the box.
Write a review before the 14 days are up - maybe say his communication was friendly etc.
You always have right of reply if need be if he mentions reasons he checked out early.
I had a Guest earlier this year who for business reason's returned to his home country after a couple of days.
I asked him if he wanted a refund which he said not to worry about it as can be picked up on business as an expense.
I wrote him a review & he never wrote me one but that's fine.
He visits NZ from time to time & was an all around polite person.
All the best
