I did two programs (Spring 2014 and Summer Alumni 2015) I lived in a Patterson 3 bedroom both times and loved it. More roommates the cheaper the rent usually. The Commons is very nice but is usually for International Programs, it has a market and washing machines in your unit. Patterson does not have bus stop but is a 5 min walk (if that) to the Chatham bus stop. Often times it may be a closer walk than some of the Chatham buildings. Feel free to message me with any questions!
