Don't use "white noise" - it can help you get to sleep, but keep you from getting to deep sleep and staying there.
Use ear plugs and an eye mask to block out all light and all sound - at your head.
If the windows could be further dampened for sound, consider that. Maybe using foam rubber with double-stick tape on the back could help.
Let me know how you are doing - I want to be sure you get this solved and get enough deep, restorative sleep.
