I stayed at Charlie's AirBnB last week while on a business/personal trip to Chicago. I had to book last minute for various reasons, but Charlie was able to accommodate the last minute booking which was a life saver on the trip. As advertised, the unit is right next to some railroad tracks, so best for heavy sleepers or those with earplugs. Otherwise, the location near the south loop is very convenient for getting to downtown quickly for business or leisure.
