Jozef & Robert's place has three key elements for me: Location, Cleanliness and Security.
Location: It is literally two blocks away from the metro station, and it takes around 45 minutes to get to Millenium Park from the train station. There's a Walgreen's and a CVS a few blocks away from the house. Also a McDonald's in case you're hungry!
Cleanliness: The place was property clean when we arrived, and the guys provide all the basics: Hands soap, toilet paper, dishwasher soap, towels, bed sheets...
Security: You feel safe walking around the neighborhood, even at night! The property has a main door which remains locked, and then the place has a second door with two other locks, so you know that your belongings are safe in the house while you're away walking around Chicago.
As a bonus: Jozef & Robert are super communicative, they help you and answer quickly if you need something or have an issue, and their restaurant recommendations are very good!
100% recommended!!!
