Rafael is a truly amazing host. He always replied within an hour or so and treated all our requests seriously and with great care. Even when we found the sofa bed to be uncomfortable, he ordered a new mattress right away and it arrived the next day. The flat was in very good location, and of a very good price compared to the rest of the places in Chicago. Only one issue is that water temperature is very difficult to control - either very hot or very cold. Otherwise, the stay was perfect.
