Many thanks Jerry, the flat is spotless, very clean and well-maintained. I even made friends with fellow travellers staying there too..Charlie’s coffee and bagels-breakfasts are brilliant too, Precita park is really beautiful and full of friendly local people, the Bay Wheels bikes are 200m away, which is super convenient. Overall my long and nice stay (21 days) contributed to a very successful and fun SF experience. Many thanks for being so reactive too.
