Karen's place is a great spot to crash - nothing fancy, very utilitarian, not "social" but just fine if you just need a safe place to sleep. The chair is comfortable enough, and while it's clearly in a common space, I had no trouble sleeping there. That said, if noise bothers you, know that the train is half a block away, so it won't be a silent space. The entrance to the apartment is in a dark parking lot, which could be uncomfortable if you're new to the city and coming and going after dark (I lived in New York for a long time, so I didn't find it troubling at all). The bathroom wasn't the cleanest, but it's tiny and there are multiple people using it, so I wasn't so bothered by it, especially at $20/night, or whatever it was.
