Enjoyed our stay
I went to Chicago too see a Cubs game with my girlfriend. We chose the Days Inn because it is close to Wrigley Field. We stayed at the there from May 29 to May 31. The hotel was clean and comfortable. It is in a nice location with many independent stores and restaurants nearby. The complimentary breakfast was a nice touch. It was cool making our own Belgian Waffles. 
The Days Inn staff was great. They were very helpful in giving us directions to the places we wanted to go to, even giving us directions and maps. They also gave us advice on weather it was better to take a cab or the bus. They even told us where to get bus passes at.
The room itself was big, clean and comfortable. We were in room 421, on the northwest corner of the building. It was quiet because we were farther away from the normal street noise. The restroom was room large with a nice, modern decor. 
For guitar enthusiasts, The Chicago Music Exchange is a short bus ride away via the 76 and 11 routes. They have an amazing large selection of all the top brand guitars including Gibson, Gretch, Rickenbacker and Fender. I could have easily spent a few thousand dollars on a Gibson Les Paul if I could have afforded it.
The only negative aspect was the fact that the rest room window did not have a blind or shade covering it. The restroom got very warm in the evening when the sun was shining in from the west.
All in all we had a great experience at the Days Inn and will defintely stay there again
