Well to be honest everyone I've talked to is of the opinion that Liverpool is "bit of a dump."
Mate, most (northern) British cities are dumps. Manchester is just as bad as Liverpool imo, Leeds isn't exactly pleasant either. Not been to any of the others really so won't pass comment.
Have you not been to any open days to have a look around the University and City? You could probably pay flying visits to Liverpool, Manchester and Leeds in one weekend.
