We had a great time at Cindy's place! The house couldn't have been nicer, cleaner, or more reasonable in any way. Her ad fails to mention (I believe) the lovely garden at the back of the house, which I found to be especially nice, coming from the northeast US in March. The walk to downtown P.A. or Stanford takes about 45 minutes, but again, coming from the east coast in winter, I'd call this a feature!
Cindy is very nice and communicative, but once she let us in we did but see her again, if that matters to you. Neither I nor my colleagues have any complaints, and I see no reason why you wouldn't want to stay here.
