Maybe there is a current student out there who can post some pictures for us. Just to add some balance, when I visited it seemed to me that Hughes is really not that bad, its just...dorms. I found it strikingly similar to the dorms at my undergrad. When I toured we met a few people who had lived there for more than one year, and they all still seemed perfectly sane. They all said the greatest thing was being able to just walk right across to the law school. Plus, you can always just go to the library when the small room and depressing paint get to be too much.
Point is, don't freak out. If you don't like dorms, you won't like these, but if you are ok with them then I think you'll make it through the year in tact. Besides, Hughes is always overly in demand by people wanting convenience over comfort, so you can always start the apartment hunt now and make someone else who wants to live there very happy. Just decide what's most important for you.
