My house had a warm air dorm (windows closed) and a cold air dorm (windows open). Most of the problems with illness came in the warm air dorm.
I agree with others that sleeping in the cold air dorm was a great sleep. My bed was right next to the window, but I was never cold. Everyone had electric blankets in the winter. I would liken it to getting in a hot tub in the winter. You are warm, but still have the cool fresh air to breathe.
We had wake duty so alarm clocks were not an issue. You also did not have to fight with your roommate about what time the lights went out.
Lastly, were were not allowed to have guys above the first floor so shacking up, not an issue.
