I know this is from a while ago and I wasn't a student there but I recently lived in Fullerton and I lived in the Haver Hill Apartment Complex. The rent isn't insanely cheap but they do allow pets and it's a nice enough complex! There were also a lot of students living there.
Hi! I'm going to be at Davis in the Fall for a Developmental Psychology PhD! I can't wait but also know nobody at the school so I look forward to meeting people!
