Greg's home is a small two-story house (1890's construction) on a quiet residential street. It's true that the train tracks are adjacent to the back yard and there are chickens behind the house, but unless you're a very light sleeper you'll never really notice. None of us did.
The street is one-way and parking was freely available for us both nights, but if you're driving multiple vehicles you may have to park a half-block away if you arrive late. Very little traffic, and quiet street with several families having young children apparent. Ethnically mixed neighborhood very close to the University of Chicago. Quick access to Lakeshore Drive right into downtown.
Decor is eclectic with tons of books everywhere. We didn't use the kitchen, dining or living rooms, but they seemed reasonably adequate. There is no TV in the house, if that's a deal-breaker for you, but we never needed it. Wifi is quick and readily accessible for streaming and such. Beds were comfortable and clean, as was the entire house.
A couple things to note, though. There are no guest-accessible closets other than a large linen closet in the upstairs hallway with a bit of space for some hanging clothes. That's also where you'll find the ironing board and iron. There were a few hangers available for us to use, but Greg stores other clothes in there as well. Also, the clawfoot tub/shower is very tall and would be difficult for someone very short or with limited mobility to use.
All in all, a very pleasant rental and I would definitely consider using the home again. Greg is very easy to work with, quite accommodating, and totally unobtrusive in his chicken-tending visits morning and night.
