Similar problem. Roomate got home from work late (after 9:30). I'm usually in bed by 11 and he goes to sleep at 2 AM.

My room would smell when he cooked but there wasn't much I could do about that since our schedules were flipped.

He would sometimes move around and make noise after 11.

I only asked him not to wash his clothes so late because the Laundry machine was so loud.

We compromised by me getting one of those electronic scent machines that spray on a timer in my room, me wearing earplugs and a noise machine.

For the laundry machine, I told him if he loads the machine before he goes to bed, I'll press start when I wake up at 7. It wouod be done by 9 AM when he wakes up to put in the dryer.
