David is an extremely accommodating and a thoughtful host. He is welcoming, made sure I would feel at home to use the common spaces, kitchen, etc., and made the room very comfortable and warm with the heaters, and so on. The room is spacious with a large desk for working, and a blossoming tree right outside the window. The neighborhood is extremely safe and beautiful as well, and quite close to downtown Berkeley. I stayed here for a night before an interview, felt well rested.
