I had a fantastic stay at Nathan's apartment -- really great space, comfortable beds, huge kitchen and living room. I am working remotely and the internet worked fantastic for many video conferences, and simultaneously presenting content and talking over it. The apartment is quiet and I never had any issues with people not being able to hear me. Additionally, Nathan was an exceptional host: responsive and accommodating.
The location is also amazing; really nice residential neighborhood but still minutes from many different things to do in the area. Nathan also provided access to his own garage which allowed me to not have to deal with street parking which is really a huge boon in Chicago.
I also appreciated the kitchen being well stocked with coffee! If you're thinking of staying in Chicago and have any plans to work I would strongly recommend Nathan's place. Literally 0 complaints and only positives.
