One thing to consider might be what kind of city vibe you want! Bristol is a pretty big city, tonnes of live music and every cuisine you can possibly think of. It's very lively and you never run out of things to do, but also has quite a lot of big green spaces in and around it when you need to escape the city! Personally loved Bristol and out of the other uni cities I've visited (exeter NOT being one of them) I always think it's the best haha. Have you visited either of them? Now we are allowed to travel, it might be worth doing!
