The house is great, the ad does not reflect all the advantages it has. Is a comfy place that makes you feel warm and welcomed, lots of space and places to linger inside. Check in is easy and the wifi very capable and stable.
Corey left us some things that made our life hassle free, like the cereals, milk, coffee and other amenities.
The house is very close from a Jewel Osco so if you want to buy food and restock is easier and at good prices.
Two train stations are close too, I recommend using the Cottage Grove station, but you can use the King Cross One too. 45 minutes way from downtown and closer from other points of interests, like the Guaranteed Rate Field if you like baseball.
In conclusion I definitely recommend Corey´s house and would return if the future give me another opportunity to go to Chicago (maybe a second Chicago Marathon)
