The place was great overall.
It was very clean and organized, with all the necessities to spend a nice few days in Chicago.
However, we had a couple of issues. First of all, the king size bed didn't have a proper frame to hold the box springs making the bed very uncomfortable to sleep in.
Second, throughout our stay there was a constant beeping from a fire alarm (because of a low battery). We asked for help and were told that it would be fixed, but it wasn't. We had the sense that the owners weren't concerned with the issue.
Besides these two things it was a good experience and we had a great time in Chicago.
