in short: very convinient and great place.
details:
-) two bus lines (49, 21) directly next to it to explore the regions; pink line 5min walk for going downtown
-) perfectly to be reached from o'hare just take the blue line to western and then the 49 (or 49X)
-) safe area, I - as woman travelling alone - never felt unsafe
-) great heating, althought it was very cold outside when I was there it was always warm in the rooms
-) very comfortable bed
-) equipted with everything you need
-) tip: justin provides you wifi pw upfront via airbn, when you stand outside the building you can catch the wifi - so dont worry if you do not remeber the doorcode or need to contact without activating roaming
