Nice hotel, great location
I've stayed at the Hilton Suites Magnificent Mile many times. It is about two blocks off the MM at Delaware and Mies Van der Rohe. The rooms are suites (as you can guess) and that is very nice. The rooms are comfortable and clean. They have two HD TVs in each suite. I have two, well three, well, four quibbles. 1) The internet is not reliable, particularly in the meeting rooms. I know they have upgraded it in the hotel because when I was there in November, I couldn't pick it up in my room and when I called the help number he actually advised me to try going into the hall to see if I could get it there. In my jammies? I think not. It was definitely better this time around, but still frustrating. 2) My second quibble is that on the morning of my departure, housekeeping came into my room and made up the bed and the bathrooms before I had checked out. I found this inappropriately intrusive. I still, for example, wanted to wash up and the used soaps had been thrown out. I ended up spreading a bath towel on the bed so that I could put my suitcase there to pack without messing up the linens. I had also assumed no one would enter the room and so I had left things out that I would normally have locked up. 3) I used the fitness center and neither of the televisions on two treadmills I tried worked nor did the heart rate monitors. The television on the recumbent cycle had so few channels and most were ESPN. Again, frustrating. 4) Fourth quibble, which is just insane, I know, but I really cringe at the upholstery on the sofa in the living room. It's straight up ugly and every time I check in, I hope that someone would have the good sense to change it, but sadly, no. The colors/rugs/drapes/etc. etc. are all quite lovely, but lordy, I do not like the sofa. 
All in all though, I like this hotel a lot. It's convenient, comfortable, a good value, the restaurant has yummy food, the bar mixes nice drinks. I keep going back, but still, I wish they'd reupholster!
