You'll have the room to yourself as well as a private bathroom. It's on its own floor, so you have good privacy.
We have excellent highway access to Hwy 85 and 101, and one stop light from Castro St in downtown Mountain View (where you can take Caltrain to SF). Stanford is 15 mins away, and (Hidden by Airbnb) is 5 mins.
Parking is easy on the street.
