Sara's place is definitely central to Wicker park. It has a hotel-room vibe (2 queen beds, bathroom and closet), with the added bonus of a mini fridge, microwave, coffee maker. It also has a lovely rooftop which I highly recommend you check out.
It's very central to the Wicker Park neighborhood, walkable to a lot of food places and the Blue line stop.
Sara was also communicative! We needed another box of tissues and she was quickly able to get it to us.
Three things that I would make note of:
1) The entrance is in a back alley way, which did not feel the safest if you're by yourself at night.
2) The place window is next to the blue line, trains come every 7 min (24/7) and it's a little loud. You get used to it though.
3) The window is mostly glass cinderblock with a tiny window that can be opened, but it opens right to the train. So although it gives lots of light, you don't really have the ability to get much fresh air (unless you go up to the rooftop).
