Pros: Within walking distance of UChicago. I didn't see Karen during my stay, but saw her husband. He was very responsive. The front door lock wouldn't open because it was very cold, and I had difficulty getting in the night that I arrived. He ended up changing the locks the very next day to a keypad access system. There weren't any issues with entry after that!
Things to be aware of: There are other renters also staying in the same location and because the walls are thin, when people are walking around or talking you can hear them. Or maybe, I was disruptive when I was on the phone! Not a big deal unless you have an interview, then it might be difficult to fall asleep if you are a light sleeper. If you are OCD about cleanliness, there was hair on my bedsheets and pillow cases, as well as on the shower floor/sink/toilet. Cleanliness could be improved on!
