Great location, walls are a bit thin
We spent a few nights at this Embassy Suites while on vacation. The location at the corner of Columbus and Illinois is great -- easy access to Lakeshore Drive, within walking distance of Navy Pier and the riverwalk, very close to a stop on the double-decker city tours, etc. There's food, movie theaters, and more easily accessible.
The evening reception is a cut above your average Embassy suites. There was some selection available on wines, instead of the just one red and one white. The snacks were substantial and were refreshed with new choices as the evening wore on.
We ended up with a corner room, which is somewhat larger than an average room, and had a lake view. That was cool. Unfortunately the sound insulation leaves a bit to be desired. We could easily hear the guest in the next room coughing and clearing his throat. Fortunately he didn't turn the TV on.
You can either valet park (more expensive, but have in-and-out priveleges) or self park (cheaper, no in-and-out). We valet parked, and had a long delay while getting our car when going out to do some sightseeing. It turned out the first guy they sent didn't know how to drive a stick-shift, so he had to come back on foot and get someone else. When they finally did deliver the car they appeared to have driven it with the parking brake still partially on, resulting in a strong smell of cooked brakes. Because the wait had been so long they took one night's valet charge off the bill, so at least they did try to make up for the issue.
Oh, and taxi cabs regularly circulate through the hotel guest drop-off/pick-up point so catching a cab is easy.
We'll probably stay here again the next time we visit Chicago.
