This variety grows quite well in San Francisco, one of the apples that do, in at least in the two locations I've planted it in. San Francisco has many microclimates, the weather varying significantly from neighborhood to neighborhood. Overall it is cool most of the year with no hard frost or ice, and the mornings often begin under a blanket of fog. A real summer season always makes its promises but never manages to put in an appearance.
The other apple that grows well for us here is called Hudson's Golden Gem, "discovered as a fence row seedling at the Hudson Nursery in Tangent, Oregon about 1931" according to the Raintree Nursery website. It a very fine russet type. We are replacing our tiny tree with one on more vigorous (semi-dwarf) rootstock this fall.
