location - can't do better than this - just off Michigan Ave and straddling the Loop and Magnificent Mile plus there is a fabulous Italian Restaurant on site
Price - very competitive
Rooms - fine - some great views
history - one of Chicago's really interesting and historic buildings - stay in the tower overlooking the river
for business - great board rooms and plenty of computer stations (never a line up) and free printing
staff - very good
beds - not the same comfort that you'd get at the Hilton

The floors have not seen a vacuum cleaner for years, the garbage bin is overfull and the coffee machine still had the filter of the previous guest in.

I travel for work so my expectations of a hotel are pretty minimal- clean, moderately friendly, good local. This hotel was in a decent location, but a little further from the convention center than I would have liked, however that is not their issue.
The building itself was a beautiful, old hotel that has been supposedly renovated, however I think that might have been in the 70s. In general everything, especially the furniture, is beat up.
I was prepared for small rooms, and that was not so bad. The good news is that the view from the 35th floor was gorgeous. Unfortunately that is the only nice thing about the room. The bedding and furniture were terribly beat up. I really question how sanitary their bedding was. The HVAC in my room was so bad that I had to open all 4 windows, even in the snow storm, and I'm from the south. The halls and room had a musty odor. The carpet was stained and burned, as was the curtains.
The television worked intermittently for half the channels. It had not been dusted since possibly when it was purchased sometime in the 80's (small old tv). The walls could have used a coat of paint (room and hall).
The fitness center was almost nonexistent and 1 of the 2 treadmills was broken.
The wireless internet had an inconsistent signal.
The staff service was average, except in the restaurant. I was pretty excited about the restaurant based on a review I read, however I did not have consistent experiences. I ate there for breakfast one morning, and the service was absolutely atrocious. I had to BEG for seconds and thirds on coffee, and the frustrating thing was that I was sitting in the path of traffic back & forth to the kitchen so you think someone would have noticed. I sat in the same spot for dinner and it might as well been a different restaurant because the food was pretty good, and the service was AMAZING.
So all in all, it wasn't the worst trip, but I would definitely pay slightly more to stay at a better hotel, and will never try this brand again.

We stayed at the Club Quarters on Wacker the first weekend in April. We were in tower room 3302. Wasn't sure what to expect, but the service was great from the start. The front desk offered to make any dinner reservations we needed. We took them up on it later in our stay with no problems. We also requested extra pillows and extra towels (on two different days) and they were both quickly delivered to us. The room was a bit small, but more than adequate. The tower only has 3 rooms per floor. It is a true tower, look at the top of the building when you go outside and you'll see what I mean. I didn't hear any other guests and liked the feeling of a bit more privacy, since there were only 3 rooms. We had a riverview and could also see the Field Museum and Soldier Field from one of our windows, which was pretty neat. The beds were very comfortable. The hotel is still renovating some of it's lower floors, but didn't hear any noise. The only bummer is that the club room wasn't finished yet. It will have coffee and tea available all of the time, plus computers that guests can use. They currently have 2 computers available in the lobby, and I had no problem printing out our boarding passes. The Corner Bakery is just 2 businesses over, great for breakfast, lunch or dinner. And McCormick and Schmicks is just a block away and they have great happy hour specials M-F, $1.95-$4.95 appetizers.
We were very close to the trains (2 blocks) and to Michigan Avenue (1 block). Location was right in the heart of everything.
We would definitely stay at Club Quarters again.
