Stacy It's important that you realize that all of the pictures you have posted are symptoms of problems, not just the problems themselves. The water is likely from a roof or plumbing leak. IF there's a long term moisture problem in an under-ventilated space, and IF it's lead to growth in a mold or mildew colony, and IF that colony is of a few certain types out of thousands of possible culprits... There are a lot of people that believe very strongly that a a significant colonization of some molds can lead to health problems in humans, usually those who already have respiratory or immunodeficiency diseases. Then, there are a lot of people that believe very strongly that the mold issue has been blown terribly out of proportion by the media. We live surrounded by microorganisms everyday at home, at work, and certainly outside. Try to get the management company to fix the problems. If you, or your friend, consider it so much of a problem, leave. If you thought your last apartment was such a disaster, why didn't you try to keep your friend out of it? Also, if things were so bad, why did you stay in the same complex, with the same management company and owner? Good luck.
