As many others have noticed, a quality of this hotel is its location. Excuse me, "THE" quality, as in, there are no other positive attributes. The lobby, of course, is beautiful, and the price is a scam, fooling travelers into thinking that the rooms themselves are worth something.
The room was not as large as an average hotel room. The bathroom was about as large as a closet. There was barely any room for our toothbrushes. Sitting on the toilet resulted in hitting your head against the sink. The shampoo and conditioner were combined in a small bottle. Even no hooks to put your clothes when you shower.
This applies to the room in general - poor and old equipment. Not enough light, noisy fan in the bathroom wakes up everybody if one person goes to the bathroom at night. There was even no folding stool to put your suitcase on - an item normally found even in the cheapest hotel rooms.
The WiFi costs about $10 per day PER DEVICE. According to the information book in the rooms, the use of the business center is charged per 15 min intervals. We did not try it ourselves though.
There is no complimentary breakfast. You can purchase breakfast for $16 per person - still less than you'd be paying for two laptop's internet connections for one day!
With no complimentary breakfast, we were still charged extra $25 per night for a third adult in the room. It did not result in any additional towels, soap, or blankets. I know the charges for an extra people are usually to cover the "extra ware" of the rooms, but the room we stayed in in the Congress Plaza was not renovated since the Chicago fire.
The hotel's website states the parking is $35 per day (more if you use valet service), but the price is actually $39 per day, and if you use valet service once upon arrival, you are charged $44 per every day of you stay. This includes Sundays, on which Chicago parking is generally free. The parking is until 2PM at the day of checking out, regardless of the time you checked in.
One good thing about this hotel (in addition to location, of course!) - the check out is at noon, while in most places it is 11AM. Honestly, cannot think about anything else. We stayed there for three days and hates every moment of it.
