Price to high; service in some areas terrible; breakfast no good.
Overall:
Rooms - Clean but VERY small (except sitting area)
Bed - Comfortable
Service - horrible (except for the front desk people and house-keeping)
Food - Not horrible, average at best (unless you don't mind a lot of white/simple carbs)
Location - Really good ( you can get a CTA pass around the corner at the CVS) and use the public transportation OR you can walk to many things since its close to Magnificent Mile, etc.
*** read the last paragraph for more tips on where else to stay in comparison to ratings… will save a lot of time and cost the same amount as this hotel if not less some times.
Rooms were clean (with no bed bugs… I checked). As others have stated, there is noise from the fire house (we stayed in a corner room on the 17th floor east side of building… with decent view)… although the noise isn't terrible at that level (I am a light sleeper and it was okay for me) and it wouldn't last more than a few seconds before trailing off.
Rooms were very cramped. The ends of the beds are approximately 1 foot from the wall so you can barely squeeze through. The saving grace on this room was the sitting area they had. The bed were comfortable (even the pull-out sofa bed was better than most and was okay for comfort level… although I personally didn't sleep on it, I did lay on it while watching tv with family.
The service was Terrible with the exception of house-keeping and the front desk which went above and beyond to make are stay nice… they did a good job, but the folks that would make us not want to come back…. 
We were about a half hour from being ready when I called down to see if we could come get a luggage cart so we'd could start loading it up even though we needed more time to finish getting ready/packing the last of our things… the front desk lady said she would send a bellboy up with one. When he came he refused to leave the cart with us (even though the situation was explained to the front desk) so he took it back with him. I was in the shower when this happened so when my brother and sister-in-law told me about this, I immediately called down to the front desk and explained what happened… she said she would speak with the bellboy about this and get a cart sent to us.
We waited and waited. About a half hour later I called down to the front desk and asked if she had spoken to him and she said she had and was surprised that he had not gotten it to us yet. Before we got off the phone, I decided to check outside the room and there the cart was… he apparently felt he didn't need to knock (maybe he was angry that we were getting the cart and he wasn't getting a tip out of it?) to let us know it was there… maybe he felt we were telepathic and could sense the cart outside the door? This situation is ridiculous for the amount of money that we spent on the room… lets be mature about this bellboy.
At breakfast my brother and sister in-law went down in socks (no shoes)(I personally wouldn't have chosen to go in socks myself, but to each their own). Apparently they refused to let them in and were 'militant' with their statement about shoes and just plain rude. Now don't get me wrong I understand if they are serving hot food and have dished that might break, that there would be a rule for safety, but there is a little thing called tact. My brother and SIL are some of the most laid-back, sweetest people you could ever meet and it is EXTREMELY difficult to offend them, but this staff member did just that.
Breakfast itself was a joke. Yes they give you a bit more options than donuts and bagels, but when they say you will get a hot food, I guess I expect it to be at least warm. I think this is a health-code violation to serve eggs at that temperature. The first day the eggs were decent, the next day they had a bunch of peppers, ham (I think), etc. (which when opened up looked more like someone had puked in it) in their barely better than cold omelet. They should realize that not everyone can eat peppers and that scrambled eggs are the safest bet. This is definitely not a Vegetarian friendly location (although I am not vegetarian) unless you don't mind eating a bunch of which/simple carbs for breakfast.
For the same price we cold have stayed at the Hampton Inn across the street… we decided to cash in some credit card points for a certificate for a Marriott hotel to reduce the cost of our weekend excursion… next time we will use the points for something else… Stay at the Hampton Inn… never had a bad experience with one and have always had great service, comfortable bed and room, and great breakfast! Also, they are rated 11th & 16th (there are two in the downtown area) and the Springhill Suites are 54th. Same prices and star ratings too but trip advisor ratings make it 11th and 16th… amazing. Shows you something about them.
