I did my BA at UCSD, class of 1980 when the school was a whole lot smaller than it is now. The school has a broad array of major and minor study programs including hard sciences, music, theater and dance, and visual arts. I majored in Psychology and did a minor in Visual Arts, mostly film criticism and video production. The faculty includes a lot of very accomplished professors. Many faculty members are hard-core liberals but there are some conservatives who mainly keep quiet. The medical school is outstanding.
The neighborhood is great. Close to excellent beaches and very low crime rates. Clean, fresh air almost constantly.
There is now trolley service to the campus to and from points south, also city bus lines stop near and on campus.
There are a few various Christian churches nearby, a few Jewish congregations, a small LDS church and a major LDS temple.
Medical facilities in the area are excellent, featuring UCSD's own medical campus, Scripps Memorial Hospital, Scripps Green Hospital just north of campus, and several medical office buildings very close to campus. (When I was an undergraduate I often availed myself of the Student Health Center which offers many free and low-cost services.)
About all I can say that's negative about it is that parking can be difficult.
