When everyone says the L is loud, it is indeed LOUD. Even earplugs didn't really help, but the train is not very active at night so it wasn't too bad. Charlie was great and check-in was a breeze. It's hard to tell from the pictures, but it's actually a pull out couch you sleep on with a 5 in or so mattress. I weigh 204 lb and I could feel the bars from the support pressing on my hips when I was sleeping. The comfort of the bed was probably my biggest complaint; I did not sleep very well any of the nights I was there because of that. The bathroom is also very tiny and you definitely can only have one person in there at a time. The AC window unit worked well and we were cool at night, but it does leak and will get anything you put on the window ledge wet. The location was awesome and we were able to walk to most attractions. The City Pass is highly recommended if it's your first time visiting Chicago and you need things to do. Many of the activities included with the city pass are walking distance, which was awesome. There is also an Amazon locker on the same block if you need to have anything delivered during your stay.
