I had to write in several conditions on my lease that had been promised to me when I looked at the apartment. After moving in, I found the unit had been hastily "rehabbed," and found my closet full of paint buckets and tools and screws on the floor (which were never claimed later).
When I needed to move out before the end of my lease, I offered them numerous subletters/reletters, and they denied every single applicant, essentially eating up several credit application fees without any results.
Claimed they never received a forwarding address, and despite my calling numerous times never sent me a return on my security deposit. When I finally was able to prove that I had informed them (repeatedly) of my change of address, they sent back only a portion of my deposit with vague listings of damages that did not exist when I moved out.
Saw several other residents' units, which had gaping holes in the ceiling, water damage, etc. Stairwells and common areas were very poorly maintained.
