We loved staying at Hans and Helen's place. It was perfect for our family reunion. The place is very spacious, modern, has a beautiful patio, and is very accessible to/from Michigan Avenue.
The location is great, in a very quite, nice neighborhood. One block away from both a bus station and the train, walking distance from a few coffee/breakfast places and a CVS.
Hans is an awesome host, very helpful, and was available at anytime we needed him. Gave us some suggestions on places to go and eat.
Would highly recommend renting this place, and will definitely stay there next time we are in Chicago.
