When my sister got married last summer, our stay at the Sheraton Hotel was delightful! Billy and the kids and I were exhausted after the long flight from San Francisco, so it's a good thing that we found the perfect place to relax! The kids ADORED the indoor pool, Billy couldn't stop talking about the beautiful jogging path, and I even pampered myself by taking advantage of the massage therapy before the big day. The reception dinner at Shula's Steakhouse was fun and delicious. I would definitely recommend this hotel to any one who is in Chicago for an extended visit!

This is a great hotel! From the doorman who greeted us as we arrived, to the young man at the reservation desk to the young woman serving complimentarily wine, everyone was very friendly and helpful. We were "strangers but for a minute!" The room was extremely clean, well appointed and we had a pretty view of the Chicago River, especially enjoyed from the large window seats. Loved the purple polka-dot paper on the toilet paper roll! Hallways were large and quiet. The restaurant next door, South Water Kitchen is very nice too. The location is in walking distance of the theatres, parks, the river (take a cruise), Michigan Ave. It's ideal. The only negative is that the concierges were not nearly as friendly or inviting as the rest of the staff nor were they very helpful. For a self-sufficient traveler, you wouldn't really need their services (although it is nice) but for someone coming to Chicago for the first time, a concierge can be very helpful. I would definately stay at this hotel again and would recommend it.

I was looking forward to staying here for my wedding in late September, and was surprised by the signs of hard times that were subtle, but affected me and my husband. For example, he got locked out of our room 2 times, once having to wait for 15 minutes in the hallway after going to the spa. The other time was when he was getting ready for our wedding ceremony, so that was stressful because he lost some time. The keycard just would stop working. Then a fuse blew, so we had no power while trying to get ready. It happened to me also, coming back from the spa, and I called on the hallway phone to get help. Luckily, right after that, an employee who was randomly walking by asked me if I had been waiting long--as if she knew this was a problem. I said no, and she called down to check. Apparently, no one had even called Security to get me back into my room! She had a set of keys and let me in, thank god. Then, on our wedding night, my husband wanted to order from room service. It was a little after 10:30pm. We were told that room service was closed for the night--even though all the literature in the room brags about "24 hour dining." That fact was never communicated to us when we checked in. I feel like the quality of service and amenities are slipping. We later heard something about a lot of employees getting laid off, so maybe that's why people weren't too intersted in providing good service. I don't think if I would recommend that anyone stay at this Fairmont nor will I ever again. BTW, the spa is great to hang out in, even if you're not doing a massage.
