Great location- I stayed here for business/sightseeing and it was right next to UChicago Medicine (you can take a 10-15 min walk to the hospital or take a bus) and next to the L stop if you want to go into the city.
Karen is very helpful and responds almost immediately if you have any questions. Her place is lovely and clean. Highly recommend staying here especially if you have business to do at the hospital but also want to be next to a quick getaway to the city.
