In a word: BUGS. The place is overrun with roaches. Also, I had bed bugs at one point, but they did seem able to get rid of those, though I have heard others say they weren't so lucky.
Some of the neighbors are pretty scary. Cops were there a lot and I heard yelling and fighting quite often outside my apartment.
The place is poorly insulated and the noise is terrible.
Don't even go in the laundry room, it's gross.
And an important word to the wise: Don't trust the staff. Get and keep copies of EVERYTHING.
