Its probably somewhat difficult if she is looking for a late summer rental right now–6 months out. Have you/she checked the housing boards at Mills or Cal? There are often people who post there looking for students to rent rooms. If she wants a place that is charming/funky/urban Berkeley/Oakland/Rockridge, it is not easy. If she is looking for something newer or more southern-california-suburb-like, she might want to look over the hill in the Walnut Creek area. Its on the BART line and only a short ride to Oakland.
