Think beach house and you will be happy. The decor is very spare, light and airy - and immaculate. There are many bedrooms; the beds are comfortable and have cozy comforters. It can be cool at night. The plumbing is not modern, but is usable. The stove is historic, but we had dinner every night, sometimes for 9 people, prepared on it. The Keurig coffee maker was heavily used.
The house is freestanding with flowering trees in its tiny front garden. You can reach out a window and pluck a ripe lemon. The street is only one block long with no traffic, so it is extremely quiet day and night.
But the Mission Park with iis playground and walks is only a half block away. Even closer is a fabulous small grocery store, Bi-Rite, which has amazing produce, meat, wine, and prepared food. A few feet further on is the Tartine bakery with its ever-flowing coffee and pastry. Buses are all around; the street car to downtown is on the other side of the park.
If you are travelling with a family or group, this is one of the best houses in San Francisco for a stay. Again, don't expect everything to be super elegant or modern, and you will be happy. I have pleasant memories of the beach houses we have stayed in, and this house fits well in that category.
And lots of good books - like a proper beach house.
