William is so great! He is so considerate and kind. House is very cozy. You will love here if you want to experience how American house looks like. I think neighborhood is safe. I've stayed in William's house during Lollapalooza week. I walked neighborhood around 01:00 - 02:00 am, but nothing happened. Sometimes, there are one or two mumbling people on streets but that's common in everywhere in Chicago. The only thing you should consider is that it would take 60 or 90 minutes to get to the downtown. It's like commuting. However, considering how lovely this place is, I think you will love staying here. There are various ways to get to the downtown via metro anyway. Bed is comfortable. I had a great Lollapalooza week here.
