Large, private upstairs space with its own bathroom & shower in a quiet neighborhood. A few blocks to corner markets and a couple restaurants, and about a mile to more restaurants and bars. I frequently used Lyft/Uber, but there are also some bus lines a few blocks away. As noted, the area might not be the safest after 10pm but is fine during the day and evening.
The downstairs roommate is very pleasant and accommodating. Kent, the owner, was away but very considerate in his communications. The house is a little old with a few spiders, but the fruit trees and vegetable garden are impressive, as are the views of downtown Oakland and distant SF from the 2nd-floor windows. A good deal for your money for Oakland.
