I was there in January & the cab cost me $50. From the airport
No idea how much taxi fare is but it took us 40 minutes to get there from Ohare, mostly just because of traffic.
I took the commuter train downtown. But if its O'Hare I would say with med traffic maybe 30 mins and a $40 dollar ride. Its 2 blocks from the lake by the John Hancock tower. Call the hotel and ask where the the nearest and color cat line stops since it's also near Loyola campus buildings. I think it's the red line which runs from ohare to downtown. And is safe. If its midway airport cab is your only way it's too far south and safetywise not a good choice. Hope this helps you, have fun !
