Im living at uwe too, I am in the Student village, the expensive halls, if you can afford it I guess it is worth it however I can safely say I would rather have an extra £1000 in my pocket and not have the en suite.
I know people living in both types of acc plus also off campus, it all depends on how willing you are to commute, you will be on Frenchay, the main campus, though I guess you know that, but there are houses dotted around the area if you wanted to spend a little less but dont mind traveling every day.
