The room (and the whole house) is very clean and quiet. You can find almost everything you need in the house. It's about 2 minutes walk to the the public transit (bus stop and train station). I walked in the neighborhood around midnight and it looked safe to me.
Rebecca is the best host ever. She made sure I have a good time in his house and in Chicago. She was so kind to show me the city and also looked up for the details of activities I wanted to do. I couldn't imagine a better host. I wish I could stay there for more than 2 days.
