We brought our giant rottweiler and she had a great time. Small rooms, but this is normal for the chicago hotel scene. Lots of interesting amenities in the room. Convenient to theatres and downtown restaurants and shopping. Really loved the lobby -- a great place to hang around or wait for someone. Lots of nooks and crannies and little tables and sofas everywhere. Watch out: The concierge (like all concierges at big hotels) will direct you to mediocre, large restaurants where they get kickbacks. We have stayed here several times and I always check for rooms here when I travel to Chicago. However, the hotel is often full so book early.

We were hungry and tired when we checked into the Chicago Sheraton. The nice clerk at the front desk got us checked in efficiently and with a warm smile. He made us dinner reservations at Shula's (giving us time to shower and change) and arranged for a bellhop to take our bags up to the room for us - what service!! We enjoyed our steaks and the bottle of wine that was recommended by the waiter at Shula's - truly a lovely meal. When we returned to our room we were delighted to find that the towels had been replenished and the bed turned down! We enjoyed the view from our room before turning in and having a very restful night's sleep in an incredibly comfortable bed. KUDOS to the Chicago Sheraton for getting everything just right!

I stayed three nights recently at the Hilton Homewood Suites- Downtown Chicago. Overall I can't rate this establishment highly. The person at the front desk was disorganized- and took over 10 minutes even to find my reservation. Once I finally got my key, the desk person just thrust the keycard at me like she was happy to be rid of me. It didn't get any better when I got to my suite. The bed was poorly made, and I found a couple of long blonde hairs on one of the pillows. The room was very stuffy, and I swear might have even had a vague pet smell. My shower was not very clean- notable hard water stains on the shower door,and the bathroom sink had a small continuous drip. Also, the carpets didn't seem fresh and even had high traffic dirt noticable. I also visited their small gym/workout area and was disappointed there also. It had limited equipment that was in poor repair. The floor in there was even slippery, which made it a definite trip hazard. While the indoor pool looked good, as I dipped into it, the water felt a bit slimy and did not have a good smell. All in all, the amenities, the unfriendly service, and the sub-standard cleanliness makes this hotel one I would definitely not recommend to anyone. When that is paired with their sky high room rates, it's just not a place that should earn any repeat guests.
