First night 'home'

I'm going back to the city in a few hours, and I'm going home tomorrow. Tonight, I am going out and about and then sleeping at my brothers place. It seems so sketchy... he just moved in two months ago. He rents one room (with no lock on the door) in a foreclosed house. A crackhead is paying the 'landlord' to sleep on the couch for a week or so until he goes to reentry. It's somewhere in the middle of Queens, cockroaches are everywhere, and my brother sleeps on an air mattress that is deflated by the time he wakes up. I haven't seen it yet, but from what I hear, I've squatted in better places than this. I should be nervous, but I am really so excited to see what it's like.
