I stayed at Ryan's place for close to a month and I am extremely happy that I chose this place.
First of all, my hosts were really friendly, open-minded and attentive. They made sure I had everything I needed and offered their help many times, without being intrusive. They also washed my laundry every other week which I appreciated a lot. The room itself is very quiet and has its own bathroom, so you have a lot of privacy. Also, it is very nicely decorated and there is a fridge, a microwave and some other utensils. The bathroom is well-equipped, with lots of sense for detail and of course totally clean. The Wifi works perfectly and the desk right next to the window is a very good place to do some work. Two very well-behaved dogs are living in the house. They are playful but would never enter my room as they are professionally trained.
During my stay, I was working on the University campus, which is conveniently located at approx. 20 mins walking distance. I enjoyed walking to the campus and never felt unsafe in that area. I really had a very good time staying at this place and I am highly recommending this, especially for anybody working on or near the UChicago campus. I will definitely book this place again next time I am in Chicago.
