We thoroughly enjoyed our stay at Heather's place. The location is ideal, the place was spacious and clean, and Heather was flexible in offering early check-in which saved us needing to figure out where to store luggage for the morning. The one drawback we encountered was a building-wide issue with the gas, which affected heat and hot water.
But Heather was diligent in working to get it fixed, quick to offer alternate accommodations and extra heaters/blankets, and she offered an appropriate discount on the price as a result. I would definitely recommend this spot for a group looking to visit Chicago.
