Kirsten and Frank are both very welcoming, and you will directly feel comfortable and "as you were home". Also, they can provide you with a lot of advice about the area.
About the location, you will be close to the Caltrain (California Av station, and you can go walking). If you borrow one of the bikes or have your own bike everything you would need is really super close (groceries, else). If you have to go to Stanford: it could not be better. The way to go to Stanford is super easy, and it takes 20minutes biking (max).
Also Kirsten and Frank's place is truly a lovely place! The room is very cute, and you will have everything you need in the house in particular to cook. Finally, the garden is really the cherry on the cake!
I spent more than one month here as a visiting student in Stanford, this is an ideal place.
