My son and I stayed here while visiting Chicago for a few days. It is a great apartment in a nice, quiet neighborhood. Viviana was quick to respond to questions and very helpful. Having access to a washer/dryer and the kitchenette was very nice.
It's a 10 minute walk to the train station, plus there are restaurants and convenience stores within walking distance.
The only negative I had was the slight odor, I assume from the cat. We have cats at home, so it didn't really bother us. But if you aren't used to being around them, it may bother you.
I would definitely stay here again.
