In reply to maxbg:
Location tends to be dominated by rent costs. Bristol is not a cheap place to live. That said, it's a great city and not just for the climbing.
TCA is great for bouldering. Redpoint and UCR are both excellent for roped climbing. Not been to Bloc so cannot comment.
I live in the NW of Bristol (Westbury) and manage to get to all the climbing walls within a 15min cycle.
NW Bristol is also good for a 15min walk from home to the Avon Gorge.
Hope it works out for you where ever you decide.
