I want feedback from other owners, this is my story...

I've been renting my Cape Cod home for 5 yrs, so, I'm a fairly seasoned at renting.  I have to say, I've had 4 good/great years up until last year.  Last year I rented to this person who was incapable of following process, he sent deposits to the wrong locations, they were also late.  Then a storm was approaching during the week that he secured and he called me numerous times wanting a refund prior to the storm even hitting.  I pointed out while discussing/debating with him that my storm cancellation policy is clearly stated in the contract and that the storm was hitting on a Sun and he was arriving on a Sat.  He had the option to arrive after the storm or early and ride it out - I warned him that it would be uncomfortable should the power go out and left extra flashlights, batteries and a radio.  His argument was that the roads may close while he's in transit which is total BS, he was clearly looking to stay at my home at a reduced rate.  To top it all off when he left the place was a mess!...It too me 3+ hrs to clean it when the norm is 1.5.  I have other issues I could site but I think you get the picture.  I never said anything to him last year as I just wanted him out.  So, last week I receive an inquiry from this guy.  I'm wondering how to respond?  I want to be blunt and just say "I have no interest in further business with you given my unpleasant experience last year" and call it a day.  My wife thinks I should create an excuse but knowing this guy he will continue to hound me.  He is very pushy and I just don't want to deal with him.  Thoughts??  Thanks for any advice.
