A great place to stay. The bedroom is at the back of the unit, so there was no street noise. San Francisco's big, so you can't walk everywhere, but the apartment is central, and steps away from a #5 Muni bus stop, which runs the breadth of the city—so convenient. There's no stove, but there's a coffee maker, microwave, dish washer, a great toaster, and a full-sized fridge! One (very minor) downside is that there's no bedside lamp, so if you read in bed, bring an e-reader.
The absolute highlight of the apartment, though, was Donna. She's a wonderful host. On our first day, she bundled us into her car and took us grocery shopping, and even bought us special decaffeinated coffee. On another day, on hearing that we'd been planning to visit the de Young, she drove us to Golden Gate Park, pointed out some sites (including us all getting out to look at the bison) and then used her membership to get us into the museum as her guests (with access to the special exhibits)! And throughout our visit, she was more than happy to give advice about where to go and what to do and how to get there.
