We just finished our family "staycation" in Chicago and had a wonderful time at The Fairmont. The staff was extremely attentive -- from the time I made the reservation to our final breakfast at their lovely restaurant, Aria. There has been a recent renovation and the room was decorated in a clean, contemporary style. The view from our room was fantastic -- the lakefront, Navy Pier, and Millenium Park. We also used their spa facilities which were relaxing, provided everything you could want in a spa, and were spotless. I would highly recommend The Fairmont to anyone visiting Chicago.

Simply a nice place to stay... I had a great deal for the room, and was impressed with the quality.

Hotel staff was very helpful; they were able to let me check out and helped me print boarding passes.

Negative: It is frustrating that nowadays you do not have free internet in most hotels and it's the same here; you have to pay for the internet.

Negative: Loud on the phone you may hear your neighbors on the phone, or them shower.

My husband and I planned a "stay-cation" to this hotel. The MySpa services were excellent and convenient. Our view was lovely (30th floor). The room itself was a little small. The bathtub was awkwardly small to take advantage of the "bath sommelier" service. Perhaps other suites are better suited. Overall, a nice escape. The decor feels a little Ikea, and almost cheap. The bed was fantastic.

Just returned from a stay at the Fairmont with my kids over spring break. There was a great special on the Fairmont site of buy 2 nights, get the 3rd free. With that they gave $100 restaurant credit, $50 spa credit, and discounted parking of $25 per night (regularly $49). Arrival and check in no problem with excellent service from the time I originally made the reservation until we checked out.
Rooms were great size for a Chicago hotel. Decor very simplistic with a Euro style flair. I liked the shower stall with door as I always hate at hotels having water pool all over from shower curtains. Nice large bathrooms with Miller Harris toiletries (my daughter's hated the shampoo but I'm thinking it was the low flow from the waterfall showerhead). There was a closet with in room safe however drawers were almost non existent (our room had a padded bench with two pull out drawers and there was one nightstand drawer and that was it). I did like the padded window seat for catching a glimpse of the lake (blocked mostly by buildings though). Bedding was very crisp and comfy and I always love hotels where they have bathrobes.
We used our $100 credit for breakfast. It covered one breakfast for three adults and one child and with tip was $98 so certainly not the amount I normally spend on breakfast. The other two days we walked to the AON Center next door and there is a Starbucks, and Au Bon Pain, and another little cafe for breakfast. Didn't try out the bar but definately liked the vibe of it.
We pretty much did museums on our trip mixed with a little shopping. Had to take cabs most every place. We did decide the first day to walk to the Field Museum but.....probably wouldn't again. Didn't realize at first but it was about 2 1/2 miles to get there. Within walking distance we found a Giordano's for fantastic stuffed pizza and it's also walking distance to State Street shopping. First time I've stayed this far south and it was a good locale since we only needed one trip up the Mag Mile for shopping the first evening. Just wish I could have found more evening restaurants around the area which is what I felt was lacking.
If you sign up for President's Club (it's free) you get free internet service. Utilized it but had a heck of a time as the connection from the nearby Hyatt kept overtaking the signal from the Fairmont and I kept losing connection.
So in all, a very nice stay. For what I paid for the place it would be a five but if I paid over $200 per night I'd probably give it a 3. So I'll average it out. As mentioned, service was a 5. Decor just wasn't my personal preference and wish there was more within several blocks.
