A mixed review--Good & Bad
We had the opportunity to stay at the Holiday inn Mart in Chicago last weekend as fifteen years ago we used to stay there repeatedly until it had slid down hill. We thought we'd try it again remembering a great view and reserved a river view room for two nights to try it again. The first negative impression was parking in the "handicapped" parking area in the lower level and walking down a terribly long hallway treking our way to a series of elevators to finally get to the lobby which is not terribly fun when you can barely walk. Getting to the lobby we found a less than cordial individual who quickly provided the keys to a room with a "view anything but the river" finally he grudgingly did switch us to a room with at least some view even though not that expected. SO TO SUMMARIZE THE BAD PART ACCESS SUCKS AND THE DESK CLERK WAS IRRITATING AND ARROGANT ENOUGHT TO DISCOURAGE ANYONE FROM RETURNING.. 
AS FOR THE GOOD...we ordered room service and it was excellent and prices were fair. The room was very clean as were the halls and other areas. The buffet breakfast was good although not worth $20 and the rest of the experience was fine.
We may try again as we are in Chicago often but will likely park elsewhere and cab to the Hotel as they don't appear to have valet parking here and the walk is a killer for anyone with a handicap. We would also recommend that they admonish their clerks to attempt the professionalism and courtesy we have always encountered at all other upscale Chicago Hotels as they are the first impression a client encounters.
Try it but take your walking shoes and ignore arrogant clerks
