The English Language Centre Bristol: Course Quality and Housing Options?

Hey there! I'm considering The English Language Centre Bristol for my English course. Can anyone vouch for the quality of their teaching? Also, I'm looking into student accommodation near The English Language Centre in Bristol. What are my options? I've come across Uninist - they claim to offer the best student accommodation in Bristol. Has anyone stayed with them? What's the cost of living like in Bristol for students? And how's the social scene? Any tips on balancing study and exploring the city would be great!
