the area around JPH is not the safest, so i wouldn't live there, try to get a place in hyde park very nice n safe area, also easily u can take a bus to JPH, other than that in the daytime its not bad nothing really going on.
I would suggest looking online so many options to rent in chicago u dont have a problems finding realtors or landlords.
