Enjoyed an excellent holiday in Brian and Leah's apartment. The apartment was clean and spacious with all the amenities required for our stay. This included 2 double bedrooms and a large living space with separate shower room/toilet and wash handbasin, free wi-fi, cable tv, and patio area at rear with BBQ, washing machine and dryer. San Carlos Street is quiet and secure, although area around Mission Street on the way to the BART can be a bit off putting due to large number of homeless. Valencia Street is much nicer with plenty of nice bars and restaurants. I am happy to recommend the apartment as a great place to stay in San Francisco and is very convenient to the city centre.
