It is best to be away from everything. I once had a cabin by a crew door which they would open and close with a bang several times every morning. I finally put a sign up on it. That helped.
Laundrys are not inherently noisy unless people are chatting - OR if they have a door (most don't these days). So nearby is good, but I wouldn't want to be across from it.
I see your ship just has the bottom floor of the atrium amidst a deck that is otherwise all staterooms. I see the restrooms in question. I would avoid if possible, because they are also very close to a public area.

You have to change it to "lower promenade" and see the cabins around C330
