We had a great stay at Sandro's condo for three weeks. It is centrally located, which made it very walkable to great restaurant, shops, and the river. Overall, the condo was fairly clean, but it was clear the place was lived-in (food in the fridge, toiletries on the counter, needed a new shower curtain, etc.). There were some plumbing issues in the kitchen that will hopefully be resolved, but it was not a big deal. I especially appreciated the clear communication throughout the duration of the trip and Sandro was very responsive to any questions that I had. The building and condo were VERY quiet (extra sound-proofed windows), which is a major bonus for anyone who knows how loud Chicago can be. I would recommend this condo for the location and especially if you are traveling for business.
