I met Jack only on my last day at his house but he was really kind and helpful all the time.
Everything in my staying was awesome. I arrived late night and Jack explained me in details how to get in the house, so I didn't have any trouble at all. On the next days I felt in a typical American home, with snacks, coffee and other things just as much as I wanted or needed. The house was clean all the time, the linens and towels are great and the neighborhood is nice with many options of public transportation nearby. So can't be better!
