This is an easy walk to the BART train station, we used it every day to Downtown San Francisco (under $4 each trip), purchase a clipper card which allows bus use also, staff at stations were very helpful as were all the people we spoke to on the platform or trains when we were unsure. we loved the warm room, comfy bed and local bakery. Marie was interested in our travel and we enjoyed daily conversation. The address is easily accessible from SFO or OAK airports via BART. on arrival we got a $6 taxi from Macarthur station. We recommend a ferry trip to Tiburon in the daylight and return after dark when the city and bridges are lit up. $ 7.50 each way clipper card departs behind ferry building near Ghandi statue.
