Jack was quick to respond to messages even despite my very last minute request to stay at their place. I actually never met Jack but I did meet his wife who was lovely and they are everything you want in a host. I was allowed my private time that I was in need of and had easy access whenever I wanted using the electronic lock. The house was just as quiet as promised which was perfect for me in my need of rest. Also, very competitive prices and just a 10 minute car ride away from the center of Palo Alto!
