Overall we had a very nice stay.
The flat is well located in a cool neighborhood and close to public transport to the rest of SF.

The flat was clean and equipped (it was very handy to have a washer and dryer)

It is best suited for a couple rather than a family as the living room (where one bed is supposed to be) is not quiet enough for sleeping.
The bedroom, though, is quiet and dark.

Communication with the host was simple - he helped us out with leaving the luggage after check out and was very responsive.
Thanks Arthur
