Robert and Juan Carlos - and their two cute little dogs - were very nice hosts. In my room they offered me water and coffee as well as books and maps about San Francisco. They were so helpful in giving me tips what to do and how to go where in San Francisco.
Their appartment is located in a very nice and quite neighbourhood. As a woman I really felt safe walking home at night.
Since I had a flight back home in the evening, I especially appreciated their flexibility to let me keep my luggage in their appartment until late afternoon. This made things so much easier for me.
