I stayed here for a week during my first trip to Chicago and it was pretty perfect for my needs. As many have stated in reviews and as Joan made me aware before booking, the ceilings are quite low. I'm 4'11" so that was not a problem for me at all, however for reference, if you are taller, I could stand flat footed and touch the ceiling. With it being in the basement, there was noise from other units and the stairs but nothing too bad or unexpected, the main thing I had a bit of trouble with was the furnace being in unit. It was quite loud and made it hard for me to sleep the first couple nights but after I took a quick trip to target for some earplugs, it was no longer an issue. The unit itself was as advertised and clean with plenty of towels and the bed was comfortable for me. I f you're going in the cooler months the heat works VERY well, haha. There is no thermostat in unit so I had to ask Joan to turn it down at one point and she was very accommodating.
The location was nice and felt very walkable for me as a single lady, it's also quite close to a couple bus lines and pretty close to the train (about 20 mins walking) if you're going to be using public transport. I personally rode the train most and occasionally that walk felt like forever after a long day of exploring but for the most part it was very manageable. There are also quite a few good restaurants within walking distance and a nice park not too far away either.
Overall Joan was a very hospitable host, she made sure all my needs were met and was very communicative. Like I said, she made sure I was aware of the potential issue with the ceiling and checked in on me regarding the temp to make sure I was comfortable which was nice!
Long story short, Joan was a gracious host, the listing was as advertised, and the location was pretty convenient and felt safe. I had a great time during my first stay in Chicago!
