PPM Apartment Opinions

Hey everyone! I'm apartment hunting in Chicago and ran across PPM, does anyone have any feedback, positive or negative, on them? Planning on touring some units soon and don't want to go in blind.

Also, on that note, I'm looking for a studio/1bed within a 15 min commute (driving) to Northwestern Hospital. If anyone knows of any place reputable under $1,800, let me know :)
