Gio's apartment is situated in a cozy attic-like area that contains all of your needs: a shower, kitchen, comfortable bedroom and living room. You can tell Gio has sprinkles of his personality with a book case of excellent reads (The Power of Now, Zero to One, etc) and Chicago inspired decor, but there are also many typical conveniences for any guest such as accessible bath products, and a spacious dresser. While everything is streamlined to make it easy for you to check-in independently, but I did have a chance to meet Gio in person and he was extremely friendly and insured that we had everything we needed.
While you do need to be mindful of the slanted ceiling, I found that it wasn't necessarily a problem for my friend and I (we are both over 5'10), other than maybe getting a good laugh at each other for forgetting about them. In addition, on a hot summer day the in-unit A/C was more than enough to keep the entire apartment cool. Honestly we kept it off while we were gone in the day, and while it was hot when we returned, it only took a matter of minutes for it to be comfortable again.
In terms of the location, it's within Logan Square, which is a great "hipster"/local spot with many good vegan friendly restaurants, and dive bars. A short walk, or $5 Uber gave us access to pretty much all of what Logan Square had to offer. But the fact that there's a garage at Gio's place made it easy for us to drive to different parts of the city, and we felt reassured for the safety of our vehicle.
If you are concerned by safety itself, the apartment itself is sealed behind a gate, 2 secured doors and a few flight of stairs, so I'm pretty sure you'll be safe.
For a competitive price, you are getting a lovely, private place and Gio as your host, who is understanding, friendly, and super responsive.
