I thoroughly enjoyed the 6 days I spent at Richard's place. The house is immaculate and attractive, the accommodations very comfortable. Richard is welcoming, friendly, and helpful. He allowed me to use the kitchen and made foodstuffs available to me for my breakfasts. He encouraged me to make use of the washer and dryer. The house is right on a good bus line and a short walk to a BART station. There is a large park across the street. The house involves some stair climbing--but if climbing is a problem, you should reconsider travelling to San Francisco!
