I stayed a month at Charla's place. It was really great. Charla and her sister are always more than helpful. The flat is moreover located in walking distance to the supermarket, the bus station and the university. For beeing in Hyde Park I always felt very safe walking home (also after sunset). Nothing to complain at all and I would always return to this place in case I visit UChicago again. One thing to keep in mind is that the flat is really rather "cosy" in terms of its size. So for a month it was ok, but for longer stays I don't know (of course also always depends on what you are used to). Thank you again, Charla, for this amazing time!!!
