I'm studying at ysj currently and for my first year I stayed in the coal yard. Good accommodation if you want privacy, and is very close to ships, asda. Morrisons. Sainsburys ect. Altho I have had a few problems with management and there is very little full time security (they patrol different accommodation but are in call when needed). It is still a good accommodation for first years and priced at £176 for a standard room!
Brickworks, abode and student castle I have heard to be very similar.
Uni accommodation wise I've heard limes court I'd grest for people who prefere quiet environments and city residence is closest to uni. St John's central I've heard to be brilliant and good for social life, tho are really bad for the 3am fire alarms
