Looking for an room in Cambridge/Somerville, MA

Hi there:

I'm a climber who will be returning to college in Boston after a 5-year break. Let's just say that I felt a strong urge to go have some adventures. Now, many trips later, I'll be heading back in Sept 07 and I am looking for a room to rent.

Specifically, I am looking for something in Cambridge or Somerville, preferably within 10-20 minutes by bike of Harvard Square. Ideally I'm looking for something in the $500-600 range. I'm neat, quiet, and I love to do dishes (and no, I'm not kidding).

Anybody know of someone looking for a roommate? There's nothing better than a roommie who'll belay you every weekend...
