Where is a the Laundry Room?

Depends upon which campus: on College Lane, there is a laundrette at Chapman Hall. Whilst on DeHav I think each individual hall has their own laundry.

The one on College Lane, as Pneus said, is at Chapman Hall. What sort of details did you want to know about it?
It's pretty easy walking distance from wherever you're living on campus (the furthest is Roberts Way, and i live towards the back of it, so at most it takes me just under five minutes, depending on how much washing i have + how lazy i'm feeling!). It's right at the front of the hall, so it's pretty obvious.

To use the washing machine costs £2 (£2.20 for a super cycle i think it is, but never seen anyone use it...) and the dryer costs £1 to use.
Most students get a clothes horse to hang washing up on, but a lot do use the dryer for most of their clothes. Personally i just use it for towels and bedding. The facilities aren't great, i won't lie, they do look like they've been there for god knows how long, and don't do an amazing job, but hey, you're a student, and they do the job. =P
Also, the timers on, mainly the washing machines, tend to lie a bit. ;>_>
Don't bother setting an alarm or whatever for slightly less time than it says, as i can guarantee it won't be done by then. xD;

Anything else you want to know just ask~
