First of all, Jennifer is a great host. Very helpful and attentive.
Her property is great in many ways. As long as you have your car, this is a fantastic option. Parking is easy, nearby highway but located in quiet street.
The location is strategic, especially if Stanford is your main destination. Silicon Valley key spots are less then 30 minutes drive. If San Francisco is your destination, sure you can always drive...but the much less hassle option is to park your car in Millbrae station (20 min drive) and take BART to downtown SF for another 20-30 min.
The house is also very clean and modern, with great TV channels and fast wifi connection.
Definitely this house is on my top list anytime I come to San Francisco or Silicon Valley.
