First - Good luck getting into one of them (They are the most subscribed halls - be prepared to be put in Oxley/Devonshire)
Charles Morris is maybe the most social, second with Lyddon, just because they are big flats, so like 10 people to 1 kitchen, so there's always someone around to talk to
CV is so quiet, despite having a massive building with like 100 flats, people don't really mix
Henry price is probably the same but they have slightly bigger flats so it may be a bit better
