I stayed here for three months over the summer at an internship. Marcy is a very accommodating host, and gladly helps with advice and tips for bay-area newbies.
The common areas are a little smaller than the pictures let on, but your bedroom has plenty of space for one or two people. The kitchen is easily accessible, and I fell in love with the Chromecast on the TV.
Campbell is a cute little town, with nice restaurants, shops, a farmer's market every Sunday (fresh nectarines!) and a light rail station only a few blocks from the apartment.
San Jose, Sunnyvale, and Mountain View are all easily accessible on the light rail, and San Francisco is less than two hours away via Caltrain.
if you don't mind cats, I'd highly recommend!
