Allyson was very friendly, accommodating, and quick to reply. The apartment was clean, beautiful, and very comfortable. The location was very convenient, with the train station being just across the street and plenty of great food/bar choices nearby. The train is definitely noisy at night/early morning, so as a light sleeper I picked up Zzzquil which helped a lot. Allyson had also provided earplugs and sleeping masks! The inevitable train noise is a small price to pay for the fantastic location and amazing apartment, so I would definitely stay here again. Thanks for a great vacation in Chicago :)
