"Naturally, with such a high percentage of tourists, Chicagoans are the seeing the fruits of their labors. The average Airbnb host in Chicago is making $8,300 per year from their listing by renting out their property 77 nights per year or 6 nights per month, on average. These numbers just represent hosts renting out their own homes while on vacation or renting one of their bedrooms."
That is an average of 108 dollars a night. That is pretty decent actually.
