ok u people are very very very unlucky
they do indeed have a rat problem, my friend found a mouse in her draw in her kitchen on a couple occaisions. the whole place is filthy and the shared rooms are waaaaaaaaaay too small (about a foot between the beds) compared to shared rooms at other halls.
also pray that ur not in the basement, cos a guy died ther in 2005, they found his body half eaten by rats - and im not trying to scare you, its very much the truth.
