Kelly, Jean, and Marty all three are rude, two faced behind your back disrespectful. If you make any of the three mad they go from professional to dramatic. My experience is if Marty is smiling to your face saying, "everything is cool, that is all right," that actually means "dont turn your back, because I am about to stab you."
My experience was numerous of times Marty left no notice of entering the apartment. She walked in when she felt, and DID NOT KNOCK.
You will find living here very uncomfortable, and harassing.
