There are 2 Sonesta O'hare properties - one named Suites, the other Simply Suites - confusing for guests and shuttle drivers. Website shows shuttle pickup is outside O'hare terminal 2, door 2E, but pickup is at 2A - other end of the arrival area. When I called the desk evening of 19 Aug the night clerk argued that the website was correct, but she directed me to 2A nonetheless.
The fitness room is overly scented. Many of the smaller dumbbells are missing. There was only one 15, one 20, one 25, no 30s. From 35# and up, there were pairs.
Overall it was, clean, quiet, & convenient to airport and major interstate highways.
