I recently rented from Redhill Aviation Flight Centre, after they re-arranged their schedule to accommodate a trip I had planned that couldn't go ahead due to (unexpected) maintenance on my plane.
I had a checkout with one of their examiners who was really nice, the rest of the team was so lovely, I felt part of the family from the moment I walked through the door, despite it being my first visit. (although aviation is a very small world, and it is likely that you'll find ties on some level with most people)
I'd definitely recommend going to all the schools, taking a trial flight with each one of them so that you can make sure that the prices (surcharges/memberships/other), instructors, type of tuition, vibe etc.. suits your learning. Everyone learns differently, and people strive in different environments, so make sure you pick the one that is best for you!
