Seth and Mike's place was exactly as advertised, by them and by all of the positive reviews. The flat is great; clean, spacious, well-furnished and equipped, and very comfortable. The back deck was great for sitting, although disappointingly the cats never showed. Seth and Mike have clearly considered what guests might need, and the flat is very thoughtfully supplied. Communication with Mike was excellent, including his meeting us when we arrived and giving us a quick tour.
The neighborhood was also as described. We'd looked into the area a bit before we got to Chicago, and we had some apprehensions about Garfield Park, but the many positive reviews persuaded us to give it a shot. And our experience was very similar to the ones we'd read about. The general area is not very appealing and gives off a feeling of being unsafe. But part of the block the house is on is attractive, the houses well tended for the most part, and felt very residential. The most pleasant and unexpected surprise was how quiet the house was at night, although it was a weeknight, so your mileage may vary. And as Seth and Mike suggest, we used Lyft to get in and out of the downtown; couldn't have been easier or smoother.
We were expecting a nice flat in a sketchy neighborhood that was convenient to downtown, and that's pretty much what we found, except the neighborhood was nicer than we were expecting, and we ended up having a very nice, if brief, stay.
