This is my new favourite place to stay in Chicago! The unit itself is absolutely gorgeous, and it's massive! It's the entire top floor of the building. Lots of thoughtful details, the comfiest beds EVER, and always excellent communication with our host.
As for the neighbourhood: the place is on a quiet, tree lined side street, and less than two blocks to a main strip which has lots of amenities including a grocery store. Humboldt park is a 2 minute walk away and you can rent paddle boats and bikes there. I always felt safe walking around the area, even at night. Also easy to get downtown and to the airport.
I HIGHLY recommend this place!
