John's flat is within a very hip district called Pilsen. The lovely wooden house stands in a calm side-street. And there is not much traffic at all. Around the Blocks there a lots of nice small shops, barber shops, thrift shops, etc. in a few walk-minutes around plus very good mexican food. To downtown you will get via different ways. All of them Take less than 30min.
The flat is clean and has everything I needed. John is very helpful and takes care of how you will get best through the city and how you can save money. All in all a very pleasant stay and a good base camp for exploring Chicago.
