Manchester uni or KCL?

I’m applying for maths and statistics. I don’t know whether to apply to Manchester or kcl. I really want to go to London, and I’m hoping to go into finance after I graduate so London would probably have more opportunities rather than Manchester. The university also looks a lot nicer than Manchester. But I currently live in Manchester and have done my whole life: I want to get away, but I also don’t like change that much. My family, a few friends and my boyfriend are all staying here, so it’ll be a lot easier to see them by going to Manchester. Manchester is also higher ranked than KCL in maths. But I’ve heard the accommodation at UoM is awful, and the university itself doesn’t look too nice. I’m really stuck, please help!!!
