The room which I stayed in Geoffrey and Rich's place was spacious with plenty of storage and very comfortable. It's location close to BART allows easy access to the city and airport. There is also a 24hr Safeway supermarket 5-10 minute walk away. As hosts they were very accommodating giving helpful advice, allowing you to have your own space or join them for an occasional drink if you wished. The recent tragic fires in Napa occurred during my stay but I found the present smoke levels in San Francisco manageable even being asthmatic and the ever changing winds ensured those levels didn't rise. I found the heavy rain at the end of my stay had certainly cleared the air and have hopefully assisted in extinguishing the fires.
