The administration at Hughes Hall, has, in previous years, run some pretty hard rules vis a vis the allocation of accommodation. They are one of the few colleges that ask for accommodation deposits, and there were a few cases a couple of years ago of student being promised accommodation which was then not there when they turned up at the beginning of term, and others who lost their deposit when Cambridge university decision making was too slow for HH. They also had an unfortunate incident with a student who was just a pernicious trouble maker and some 10 years after he had been refused permission to return and complete his PhD, still frequented forums and websites, ranting on about HH. Unfair and unreasonable, but then when the college was noticeable less flexible than other colleges about accommodation in particular, its reputation was further damaged. The history of the accommodation issues and the weirdo might still be available on the grad union forum.
Many people are very happy at Hughes Hall, and it does have some very modern accommodation over-looking Fenners cricket ground. But it doesn't have (or didn't up to two years ago) accommodation for all its students and has had some pretty blunt and insensitive interactions with students.
