We came with a family of two adults and three kids for their first time to Chicago. From the very initial contact (later in the evening) I received a response within a half hour and every other correspondance was the same. The location is amazing, literally two blocks from the John Hancock. This puts you steps away from Tempo Cafe (local great breakfast spot), the Magnificant Mile, Water Tower and more. Giordanos and Rosebud on Rush are a few blocks away. The hosts recommend the parking app, "Spot Hero" and I concur. We scored parking with in and out privelages a few blocks away on Chicago and Michigan.
The unit is beautiful complete with washer/dryer combo (small loads so plan to do more if you're planning on any laundry), the kitchen is big and well stocked, and the view is great. The couch folds out and there is also an air mattress. The big hit for the kids was the old school video game which they played non stop. The pool on the 24th floor has amazing views and the lounge area is beautiful day or night. Overall, its a fantastic unit to enjoy for a couple or small family. You can't beat the location and views.
This property will be my go to spot for future trips back home.
