Eric is a cool guy! He is a traveller as well and loves to share stories. His home is spotless and the room really convenient for two people. The shared bathroom was never a problem and we never had to wait to use it. He also gave us some good advices to eat out and sights.
There are two different ways to get to town or vise versa by public transport. I shortly explain you how, becauce we didn't know the two different ways. The fastest way is to take the Metra train, which takes you about 20 minutes and costs 5$ one way. We came from the airport and bought the CTA pass which is for the subway and the bus. The CTA and the Metra are two different companys. So we came from the airport, where you have to take the CTA, Uber or a taxi and there we bought the CTA Pass. If you want to use the pass and don't want to spent the 5$ extra each way for the Metra you have to take the red subway line to the final stopp then the bus and a short walk to his house. This takes roughly an hour. Just as information :)
