Ahmad's place is an excellent value. The room is big and clean. His dog is friendly and doesn't bark. Everyone was accommodating, especially with my rowdy infant son.
Location is close to downtown SF as well as the Oakland Airport. We felt pretty safe walking in the day, but didn't dare to go out after dark. If your looking for a place that is close to shops and restaurants I would stay in the city. If your looking for a good value and a great host this is your place.
