In my opinion, Glen Eyre 100% has the best social life. You can walk to the university campus and then get a bus to any of the nightclubs which is definitely a bonus. My friend from Wessex Lane said that there wasn't much going on there in terms of social life, and wished she had chosen Glen. I think that Glen Eyre is one of the biggest halls as well which means that it can be easier to make friends with lots of different people, and there are bound to be people from your course living nearby.
