Great amenities, very comfy bed, beautiful high ceilings, nicely decorated and in the heart of Chicago. I did not sign up for the Sonder app because the last thing I need is one more user name and login. So I suspect (or at least hope) the check in experience would be better through them. Going through Airbnb it was the worst check in experience I’ve ever had using Airbnb. Once you do get through your apartment doors, you’ll be delighted and things should be seamless from there.
