I booked the hotel through Priceline and got an exceptional deal! The complimentary breakfast is great! They also have social hours in the evening on weekdays and one of the days we were there, they had a band and an open bar!!!
The location is excellent, walking distance to the shopping area. The tourist attractions are nearby too, and you can get a taxi to most of them for under $10.
2 issues: They have only 2 elevators for the 19 story hotel and we had to wait for it most of the times. Parking is $45 a day, but that is expected in a metro city.

Overall, I would highly recomment the hotel to anyone.

After reviewing tripadvisor.com I decided to stay at the Residence Inn/River North. This was a 'girls weekend" trip. We were greeted by bellmen who took our car to vallet parking and helped us with our bags. The staff was very helpful with getting us our room. We had paid for a corner city view room. They asked us if we wanted a higher floor so we could see more. (There are 27 floors) My mom was not thrilled with that idea so we were on the 12th floor. We still had a decent view but could see mostly construction. Upon entering our room we found a small kitchen completely equipped with stove, microwave, full-size ref and a small dishwasher. There was a small dinette set by the window. The room was shaped in the shape of a staple. The bathroom was nice sized with a sink and dressing area separate from the shower and toliet. The bedroom was a kingsize bed. They do not have doubles and a sofa sleeper. It was all very tastefully decorated and you could tell it had just recently been redone. It was quite and the bed was very quite. There were two thermostats in which you could control the temps in the two rooms. The breakfast was a nice offering of sausage, eggs, waffles, french toast, potatoes, oatmeal, cereals, fruit, yogurt, breads, muffins, and MORE! It was raining hard when we left. When our car was brought back the bellmen walked us to our car with umbrellas over our heads and they put our luggage in the car. It is in the heart of it all. Just acrossed the street was "Holly Cow" a Harry Carry steak house. We were two streets over from the Michigan Ave. If you want down about 4 blocks you were right at the Rainforest, Hardrock and Ginos pizza. Also, the double decker bus tour stopped right there. We took this tour and highly recommend it. It was a very nice stay and I would tell you to choose the Residence Inn/River North for your next stay.

Brand new hotel in a great location-easy walk to Magnificent Mile. This hotel was crowded, but for a good reason. The entire staff was fabulous, very nice and helpful. Great for families as breakfast is included, and there is a nightly reception at about 6pm. Right across from Harry Caray's first class restaurant. Only thing disappointing was on one side of the corner room, the view was of a hotel being constructed. Staff apolologized and gave me extra Marriott Rewards Points. Would DEFINITELY stay there again. Rate I got was $199, which I thought was real good.

We stayed one night at the Residence Inn after calling and receiving a good rate. We have stayed at many hotels in Chicago, and this topped our list. When walking into the hotel it doesn't have a lot of fluff like larger, grander hotels. As for security, at the ground level you go up to the lobby floor and check in. Then you have to take another set of elevators to your floor. The doors to your room is very heavy and seems like security was in the design. The staff is very nice and friendly. Staff even took the time to get a dog traveling with his family a bone. Our room had everything you would want in a room. They had clean silverware, bowls, refrigerator, microwave and other extras. If I had to give a negative it would be that the pool on the smaller side, with a deepest at 4 feet. Don't hesitate as this is a great find in Chicago!
