Ling is a wonderful host, she is quick to respond and conscientious and kind. It was raining on a couple of the days of our stay, and Ling thoughtfully brought us umbrellas. Her home has many appreciated amentities such as a Keurig coffee machine and space heaters. Plan on leaving some time to commute if you are going to SF for tourism as the 5 mile trip can quadruple with traffic! Overall, I had a wonderful stay and much of that was due to Ling's thoughtfulness and preparedness as a host.
