We have rented from him for about 5 years straight now, every summer. His rates are very reasonable, his units are always clean (we have rented townhouses and last summer rented a 6 bedroom pool house from him) and comfortable. Last year there was an issue with pool heat--- that we paid for--- not being turned on, and his son immediately returned my call and fixed our issue that same day. We are currently trying to decide which of his units to rent this summer!
My only, and seriously only, downside I've noticed is the mattresses in the TH's are pretty worn. Now, the house from last summer had great mattresses, but we have rented 4 townhouses, all different ones, and the mattresses left a little to be desired. They weren't horrible or deal breakers, just a little flatter than we like.
But bottom line, we have used him in the past and will continue using him in the future!
