I would write a longer review but the previous comprehensive review by Everyguy is pretty much what I would have said too.
This really is a 1 1/2 to 2 star motel - but if you are driving into town and wanting to take the CTA the free parking is good. You can only book this hotel on the internet via booking.com
On the Chicago marathon weekend I was in town there was not a single hotel available in downtown Chicago for less than $200 per night! Staying at the Amber Inn cost $65 per night and the CTA green line took only 10 minutes to get you into the loop. This is the place's main value point - this is the closest hotel to downtown at an economical price. You could stay in a nicer place out by the airport for about the same price but you will spend about an hour to get into the loop via the CTA or METRA.
