I'm sure CCC is much better, but if you wanted to live in London for example, it wouldn't be a good choice. However, London is not the best place for undergraduate teaching degrees with only few unis offering it. Most of the universities that do undergraduate ITT are outside of London or not very central, such as Kingston, Roehampton, Greenwich (which is quite central) and St. Mary's College.
The campus is quite beautiful, but far away from everything in a park (hence Trent Park).
But you can decide for yourself. Your interview was yesterday, right?
Doesn't really matter where you do your teacher training. London is good if you wanna live and work in London, but if you don't wanna do that, you can study anywhere!
