Carnegie Mellon is a self contained campus in the Oakland neighborhood of Pittsburgh. It is surrounded by a residential neighborhood, shopping, and Shenley Park. The University of Pittsburgh is just down the street.
Similarly, Case is a self contained campus in Cleveland, though University Hospital bisects the campus.
I agree that U of Minnesota, Wash U and Rice might all meet that citeria. We were just at Rice last weekend and were commenting how pretty and “contained” it felt despite being smack in the middle of a city.
