Well, from what i gathered last year, the hawthorns is a bit rough around the edges (like northwell), but it is in the centre of the uni precinct and near to park street with all its bars and clubs, so its in a very good position. Its also quite near to the union (where most of the orbital parties are, which you will be a member of being out of halls) so you don't have to worry about long walks in fancy dress or lots of taxi rides.
The reason i ruled it out last year was because you've got a very high probability of having to share a room with someone, which, may be good, or it could be very bad, it depends what your personal preferences are. Its good if you're into sharing/swapping or being shared/swapped.
