Never did, I lived in a HMO and have done every time I've been at university. Cheapest way to live and the best way, decent house and usually a better location than the halls.
Get in a HMO, bills included, stuff them the rent in blocks 10 months of the year, and usually to stay the 2 extra months you just pay 1 months rent extra.
Halls are overpriced ****e, and you'll end up living with a bunch of dickheads who shop at top man and are only there to get ****ed.
I like a good time but it's like even when I was an 18 year old there were so many *******s who couldn't handle their drink let alone act like civilised human beings after a few pints. more fussed about impressing their mates than having a good time.
