Good Location, Older "Historic" Hotel
We decided upon the Congress as we had a problem with a previous reservation at another hotel and had to make a last minute selection on a very busy convention weekend. We chose the Congress based upon location and comments that the hotel was clean, which it was and knew it was going to be older.
We used the bellman to check our bags prior to check-in and all the staff was quite friendly. After our return later that afternoon they were able to put us into a King room which was not available when we originally made our reservation. The room was large enough and had the traditional high ceilings with a building of this age. The rooms are dated however clean and again, not bad considering almost the entire downtown was sold out. If I had paid the $220+ any other time I would not have been pleased. 
We did not dine at the hotel but did visit the cocktail lounge on Saturday evening and the one bartender on staff was overwhelmed with the amount of guests trying to get service. I continued to expect help to arrive but it didn't happen and we eventually left and dined and enjoyed cocktails elsewhere. Checked back into the lounge Sunday afternoon and same thing/same gal, lots of guests waiting and slow service. We again opted to dine and drink elsewhere. 
Yes, the hotel is aged and shows it, but the location is great (across from the park and lake) and there is something to be said for that historic feel at times. Would probably make another choice next trip but in a pinch this worked.
