Aaron's apartment is a gem. The building is hip and modern and offers some great amenities. We never made it to the bar or gym inside, but they looked very nice. The apartment itself is clean and modern. The building is within 2 streets of the red L line, which will get you right downtown. We stayed for the Chicago Marathon and it was a perfect spot for traveling to and from the race. Aaron answered our messages quickly and even was kind enough to let us check in a couple hours early last-minute. Would stay again!
