I am subleasing my Single room in a 3 BED / 1 BATH apartment for $1200 a month. It is available starting January to May or June, with the option of Summer subleasing available as well.
The apartment is located on the North side, with campus right across the street (<1 min), and a 10 minute walk to Berkeley BART Station. It is nearby Brown's Cafe and Thornburg Village.
Laundry machines are available on site. My room gets a lot of natural light from the window, and the area is not noisy. There will be 2 other male housemates with their own singles. Our landlord is easily reachable and very responsive to any maintenance requests.
