Adequate and Basic Holiday Inn
I needed a decent and reasonably priced hotel for one night within walking distance of Union Station and the Holiday Inn Chicago Downtown fit that bill. Check-in was very slow but was offered a smile and an apology by front desk staff. I was also recognized as a Priority Club member and offered my choice of benefits. 
The hotel is an older and typical Holiday Inn. The outward appearance is about what you will get inside. The room was configured very strange. Lots of room with no furniture. Only chair was the desk chair. The a/c again was a problem - the older wall type unit which could not keep the room cool on a 99 degree day with the room getting the afternoon sun. Lighting was adequate. Bed was comfortable.
The fitness center and business center were both very nice and a step above the rest of the hotel. The rooftop pool area was very nice and relaxing and it was a welcome relieve to take a dip into on such a warm day. 
There is a fee for parking. It is a very easy walk to the Clinton St. metro, Union Station or the Greyhound Station. I did feel safe in the neighborhood.
The AAA price was very fair for this property and the room. The on-premise restaurants offered a variety of choices and the price point was about what would be expected. 
All staff were very nice and pleasant. In my opinion this hotel is great for a one or two night stay.
