Overall a pleasant experience. The concierge was very knowledgeable giving us a lot of good information on attractions, restaurants and helping us book tickets for the Bulls game at very short notice.
Check in staff were courteous except for a slight discrepancy in final bill which wasn't resolved by the time I left.
The hotel could do with a makeover but overall clean and importantly quiet. Service was good and nicely subdued.
Downside is that you had to pay $10 to use the gym. Doesn't this come free for guests in other hotels?
Bar service was nicely understated and very polite staff.
Overall, recommended for both business and personal travel.

Stayed here for one night on a "staycation". From the outside it doesn't offer much and feels more like a business tower than a hotel. The rooms and public spaces however are comfortable and elegant. The rooms are typical Westin but it you can secure a room on the south side of the tower overlooking the river you will have a great view and a larger room. Bathrooms nice as well. Great location right on the river and close to everything.

I love this hotel. It's elegant, efficient, spacious, clean, modern, and very well located just across the Chicago River from the Loop. The staff are exceptionally nice, the lobby restaurant/sushi-bar is cozy and reasonably priced, the rooms are tastefully decorated and clean, and of course the beds are great. For a mid-size business hotel, it really feels boutique-ish. Expect nice-size rooms and bathrooms, nice touches everywhere (like a personal computer in the room, oversize room safes, pleasant colors), and generally feeling very much at home. Even the hallways are warm and welcoming.

Beautiful Hotel with exceptional rooms. We were upgraded to the presidential floor for free. Kids really enjoyed the stay with TV,great room service and happy hour. The view of Chicago river was beautiful from your room. Close to everything Chicago stands for. Walking distance to Mag Mile, State St and a lot of well known restaurants.
