Just fix one small thing, and you're perfect.
We bought a Sniqueaway voucher for a getaway night after the Bruce Springsteen concert in September. MileNorth has a fantastic location just off Michigan Avenue and 2 blocks from a Red Line station, so if fit our needs perfectly. The lobby is beautiful, the staff was uniformly friendly and efficient, and the room was pristine and well appointed. Our only complaint was that the Roman shades in the room were down and would not go up. After we quickly dropped our things in our room, I stopped at the desk to tell them about the shades and gave the staff permission to enter the room to fix the problem. The shades remained down.
This would have been a 5-star review except for the shades. Fortunately, we live in the Chicago area and missing the view wasn't a huge deal for us.
