We spent three nights with our 2 kids (4 and 2 yo) in Matt's apartment.
Location is great: super nice neighborhood, safe, street parking, kids playground and Lincoln park zoo at a walking distance.
We walked to downtown Chicago everyday (1 hour walking through the amazing buildings or near the lake, even the kids loved it, it was a super nice way to visit the city)
Matt and Alison were very nice to us and always helped us.
Definitely recommend!
