Unfortunately, I live in a two room apartment, of which they are being nice and letting me stay here. Since it's so small when they sleep I have to sleep because when they are up I have to be up (two rooms, can't escape the noise or light) and I sleep on a cramped ass love seat/sofa. So usually, 3-6 hours at a time maybe. Anything over 5 is win. I'm used to living on 3-4 and napping in between when I find quiet lulls in the days.
