You don’t live there. I would be super annoyed if I got asked to change my nighttime routine by a visitor.

If it only mildly annoys the boyfriend, let it go and get yourself some sleep headphones. If you think he wants to say something but needs help how to do it, encourage him to write her a polite note introducing himself – and mentioning he wakes early and would she mind lowering the volume. And leave his phone number and an offer to have a cup of coffee sometime, too.
