First of all, about silva, she is a wonderful person and great host. She was in constant touch till I could reach her place. She even cooked food for me !!! While I was roaming around the city, she was concerned about my safety and return. She has motherly nature. Her apartment is just 4 blocks away from Daly City station, which equidistant from airport and goldengate or any main city place, and very well connected by city buses and BART. Her place is very clean. Great place and host for a traveller !!
