Jeffrey very kindly allowed us to drop our bags off very early so we could get straight into exploring the city.
Millbrae Station is within walking distance (about 45 minutes), which gets you to San Francisco CBD in a further 60 minutes.
We found this extremely convenient and enjoyable, we felt safe and were able to purchase groceries on the way to and from the station.
We had full access to come and go as we pleased and we found Jeffrey to be a very engaging and easy to get along with Host, making suggestions with his knowledge of places to visit / things to do.
