I stayed at Nick's place while I was in town for a meeting. Nick is a super awesome guy. He was very kind to let me leave my stuff early on in the day even before official check in.
He was also very thoughtful, putting a sweet welcome message and inviting me to pin my home destination on the world map, which was kinda cool. The place is well furnished and well stocked. I had absolutely no problem with anything. The fact that Nick's place of work was very close to my conference venue was an additional bonus, and Nick was very kind to drop me off to the conf throughout my stay.
I did not spend a whole lot of time in the neighborhood since I was in the meeting, but nothing seemed concerning. I have no hesitation in recommending Nick's place to anyone looking for a comfortable stay in the windy city. This is definitely the place I am coming back to the next time I am in Chicago.
