We had a great time in SF. The appartment is perfect, very clean and everthing works. We didn't cook, but you can if you want to.
We also liked Noe Valley, not 'downtown', but a very nice part of the town. Shops, restaurants, parc, public transport, it's all around the corner.
Sarah was quick and easy in contact. So, we surrely recommand this place to stay when you have plans to go to San Fransisco. Beautifull city!
