Student housing

I'm quite stressed about finding student housing for next year. At the moment i'm unsure who to share with as most of my flatmates and course friends are commuting next year, and so far having looked at the prices for housing in Bristol it seems to be quite expensive and caters more to UOB students, meaning most places are way too far from my uni (more specifically in the centre or the other side of Bristol). Where do people look for the best student housing?
