We had a great stay in Irena and Martins place. It was spotlessly clean, really well equipped with everything we needed, comfortable and homely.
They were great hosts, perfect communication, lots of nice touches like a selection of drinks in the fridge.
It's in a wonderful neighbourhood full of great shops, bars, cafes and restaurants, yet its quiet and peaceful. It's about 5 mins walk from the blue line L which will take you right into the centre of Chicago or to airport.
Highly recommended and would definitely return
