-- I stayed here 24 days. David is one of the best hosts I've had, and I've had a lot of hosts. He provides more basic amenities than anyone I've experienced: facial tissues at bed and desk; wastebaskets at bed, desk, and bathroom; body/hand/washcloth towels; fans and evaporative cooler; lots of pillows; abundant toilet paper supply; a desk and chair I was happy and comfortable to do my remote work at; some breakfast foods (cereal, almond milk, eggs, coffee). The room felt like David himself would be ready to live there, a simple standard that many rooms don't meet. David himself is friendly, helpful, and flexible regarding odd checkouts. There's also detergent for the house washing machine.
-- The room is large, with a nice bathroom, and a large desk. With the bathroom window open you can even get a bit of cross-breeze going.
-- Location is great: 12 minute walk from Rockridge BART and Trader Joe's, 3 minutes to Safeway supermarket and small bakery/butcher. If you like stuffed pizza, check out Zachary's. If you like sci-fi/fantasy books then check out Dark Carnival, it's an awesome but out of the way bookstore. Nighttime was fairly quiet, though I did use earplugs or fan noise sometimes; I'm pretty sensitive to outside sounds though. Relatedly, a lot of the businesses close fairly early, like the bakery is closed by 5 PM, and restaurants by 9 or 10 PM.
-- Drawbacks: for arcane reasons the bathtub can't be used for baths, and the sink hot water is quirky. (The shower was great, though.) The locks are old and annoying.
-- I would stay again.
