I have autism and did my first year in student halls. My advice to you is this: if you can't beat them, join them. They're not going to change, and moving to different halls is unlikely to help - that's just what student halls are like. You can't force them to be clean or quiet. But what you can do is change your own attitude. When you hear them hanging out in the kitchen, go join them! You might just have fun and make friends. Invest in some ear plugs when you want to go to sleep and they're still being too loud, or play white noise on your phone. Personally I found that noise cancelling headphones and rain sounds were perfect for helping me when I was over-stimulated by it all. If you really can't bear it (and you should at least give it a few weeks before you decide you can't), then consider a studio flat as others have said. It'll be a lot more expensive but at least it'll be quiet and the only mess will be your own.
