I stayed at Priscilla's for work purposes @ Stanford University. Commuting to campus is easy using the DB line that has a stop 4 minutes away from the house. I also walked a lot to and from the house, which again was easy, and also felt safe. Biking would be quick as there is a network of bike routes throughout the neighbourhood leading to main campus.
The room and bathroom were extremely clean. The bedroom was nice - bright and comfortable, with a large comfortable bed, nice pillows and a cozy duvet, as well as high quality linens. The closet is spacious and well structured. The shower has great water pressure and piping hot water. There are snacks available for purchase in the room, though I did not have any.
The house has strict and well enforced rules to ensure smooth co-habitability. I would suggest to ensure these suit you during your stay.
I did not meet Priscilla during my stay, but she was prompt in her responses. Priscilla's mom kindly welcomed me for my late check-in and was always friendly when I returned to the house late in the evenings from work.
