There are numerous hotels and Inns and AirBNB's nearby. And there are numerous ways of transportation from Birds, Subway, Buses, Rental Bikes etc
It's also pretty easy to get around in San Francisco/Bay Area. So, even if you're not close to the place, you can easily get to it with proper timing.
There are some inn's on Valencia but I am unsure of their pricing
How about parking around school?
