I stayed for 4 nights and had nothing short but a fantastic experience at John's place. The place was very nice and clean, I felt very comfortable in the neighborhood, and so many essentials were already provided. There were many amenities available at the place that I wasn't even expecting as well and really appreciated having! A TV was also available for whenever there is any downtime when you're not exploring the rest of Chicago.
John was very readily available and accommodating during my stay here and was very flexible with check in time when my flight arrival was extremely delayed. I highly recommend staying with John.
