Graduate student needs housing

Posting for a friend: I'm looking for housing for a graduate Portuguese student who will be at CMU mid september to march. Because it is not a standard time for a lease, it is challenging. And he is doing it sort of late in the process of looking. However, if you have any ideas, please let me know. Air B&B may be his only choice but if you know of anyone looking for a room mate, or someone to share a house, please let me know. thanks. Sent from my iPhone
