This is one of the best hotels I have stayed at in the U.S. The room was super and big, the bed was great and the bathroom was huge.
The hotel is close to everything, and easy to get to from the airport (ORD), the metro stop from the airport is only a short distance from the hotel.
The lounge was nice and the staff remember what they were serving the day before and ask if you want the same today as yesterday. Especially Marie from the executive lounge was great and "she has always a big smile on her lips".
Next time I am in Chicago I will certainly stay at this hotel again.

The lobby in this Marriott was enormous - sleek, modern and clean. The check-in was a breeze and luckily a room was available for my morning arrival. The staff was professional, friendly and efficient.

My double bed room was perfectly sized and I greatly appreciated the separate tub and shower. So much easier to maneuver in a stall vs. tub. The room was spotless, the bed comfortable, and the overall ambiance was classy and understated.

Many visitors usually stay on Michigan Ave. or the River North area. This property is located just a couple of blocks from Union Station, which was perfect for me. "The Loop" Chicago's financial and business district is no longer an empty shell when workers leave. There are plenty of restaurants and other attractions (as well as banks and drugstores). Chicago's second major shopping area, State Street and Millennium Park are both within walking distance.

I really enjoyed my visit here and would not hesitate to stay again.

Nice Hotel in the Financial Area. My room looked at the Willis Tour so that was an added bonus. It is very close to the L and a Garrets Popcorn. The bathroom has the shower and tub separate and it was nice to have turn down service and chocolates every night when I arrived after dinner. All the food that I had there was great as well.

Was able to spend two nights there last week. Checked-in to a king room. The room is a little on the small side; bathroom was huge though. Was placed on the interior (overlooking the courtyard; no street view). No issues whatsoever. Free internet access at the lobby. They charge you $14.95 per 24-hour period for in-room internet.

I have to say this: Great location, and very convenient. Mc'Donalds just across the street with Starbucks close by, Dunkin Donuts not too far either. Public transport within 5-min walk (CTA). Most important of all, it's close to where I need to be.

Will stay there again in a heartbeat.
