Aaron's place is great, it's an old building with a new renovated, modern/retro feel. This place is stacked with all the amenities needed and more for a trip, and very clean, like your staying in a nice hotel.
Aaron's itinerary and instructions are great and he's a message away if you need something from him. We didn't get to meet him but we didn't have too, seeing how everything was laid out perfect.
His place is about a 14 min drive to the museums and parks by Lakeshore drive.
Parking is also free on certain streets with a parking pass Aaron provides, which is also a great money saver.
I would definitely recommend this place for a weekend getaway in Chicago.
