I had a pleasant stay at Shaun's unit. I was traveling alone and stayed there over a weekend. This unit is located in a very nice building and in a great neighborhood. There is a bus stop just steps away from the building and a train station about 8 minute walk both of which made getting around very easy. There are also plenty of businesses around including a wallgreens on the same block and a whole foods in the next one. There is a really good bar/restaurant right across the building.
The unit itself is perfect for 1 - 3 people for a few days. There was good AC and it was pretty quiet at night. It felt safe and clean. Overall a great place to stay in Chicago.
