Stayed at Alejandra's place for a few days visiting Chicago. The place is clean, warm (since we were there on the winter), and cover all your basic needs. The bathroom was shared but always clean and with hot water. For the price is a bargain!
From there, it's easy to move around the city in subway, (you can get the 3-day-pass for $15 USD). Downtown is 15 min by subway. By dark hours I would recommend to take Uber or Lyft.
Alejandra was always kind and was a great host. I highly recommend her place.
