We loved Beth's garden apartment. It is a lovely space with a very comfortable bed and many quirky touches. The apartment is on a quiet street in (what appeared to us) to be a very safe area of Chicago. No problems at all walking to and from the train station at all times of the day and night. The nearest station is 10 mins walk away and it's a 30-40 minute ride to the heart of the City.
Beth is a great host and helped us out immediately on a small issue we had which was much appreciated.
I would have no hesitation in recommending this apartment for people looking to visit Chicago- we had a great time.
