I've stayed at most of the Choice properties in the Ohare vicinity, none are exceptional or repulsive.

We stayed at the Comfort on Touhy last September, IL411. Now that I think of it, it may be the best of the bunch. There's a family restaurant/diner in the parking lot. The shuttle service can be a little slow, but by the same token they are also very accommodating, going so far as to run it like a taxi service in the general vicinity. It's also a rewards night value at 8000 points through mid-September.
