I live in a dorm.
I live in a single dorm where I live alone.
No one comes to check my room except for the people that come in to clean my room. (yea I get room service ^^)
But since I like cleaning my own room, I always make them skip my room and just clean my bathroom.
I also live in a non-smoking floor, but I have a nice external fan.
I'm living in a smoking floor next year.
no problem for me.
