I have exclusively used Apartment Savvy to move into and around Chicago. As moving sucks in general, it was very helpful that Apartment Savvy's representatives have a short-list of potential units all of which are pretty doable; I suppose they are good at predicting what you want based on how often they place people.
Anyway, both times I used apartment savvy the tour was quick, I found exactly what I needed space-wise and at the price I could afford on my budget. Other free apartment services, which will remain nameless, I used prior to Apartment Savvy basically took me through the sewers of Wrigleyville despite my desire to live near Lincoln Park.
My personal experiences with Apartment Savvy have been devoid of any problems or hiccups, and I will use them again.
