We loved this house. It's full of old world charm and I'd say the photographs don't do it justice. It's extremely spacious (though with a relatively small kitchen/dining area) and has lots of beautiful features such as stained glass windows. The location is also wonderful; a nice neighbourhood with lots of good restaurants, and an easy walk to union square shops etc.
The down side of it being so central is that it's noisy but nothing that a pair of ear plugs wouldn't solve.
The house comes with a very attentive caretaker, which makes it like a well serviced hotel and was more than I'd expected.
Overall, I would stay here again if I was visiting SF with family.
