There are many factors that you have to look at, e.g proximity of your university vis-a-vis transport cost, your age group, whether accommodation off campus is shared, etc. As a PhD student, I stayed for one academic year in campus accommodation, every Friday/Saturday nights were party times for the two American flatmates would bring their friends. They'd mess up the kitchen and wouldn't bother to clean up. We were summoned by the accommodation officers on several occasions. When my contract ran out, I decided to rent an apartment outside campus and I don't regret making that decision. But take note, there are many types of accommodation off-campus which are shared, it can be the same scenario of having noisy housemates
