Petra's residence is by far the best accommodation of its type at which I have stayed in the north side of Chicago and I have been traveling there regularly for 14 years to visit my son. The bed was great, the bathroom was modern and the sitting room was perfect. Petra had thought of everything including floss sticks in case I had forgotten mine (which I had.) While Petra offered for me to go in and out the front door, there was also a back door that entered right into my bedroom that I used.
