My stay in Ryan's house was pleasant and he was a welcoming, knowledgable host. He helped my friend and I with our luggage and told us to feel at home using his fridge for leftover food. The room itself was very spacious (just like in the pictures) and it was wonderful having a personal bathroom.
The location is conveniently close to the university, however I would caution single travellers and girls about the neighbourhood. The street with Ryan's house is very decent but the surrounding area is very rough. My friend and I weren't comfortable walking outside to explore and ordered food delivery. Most areas in South Chicago are to be treated with caution, as we later learned. On the flip side, I was moving and my car was packed with my possessions, but we didn't have any kind of trouble just leaving it parked on his street.
It's a great stay overall, especially if you have car access to the other parts of Chicago. Ryan was a terrific host.
