Chani's place was exactly as advertised. We could hear the kids running about in the mornings and practicing piano in the evenings, but they weren't too bad. The separate access to the apartment through the back was useful and made it feel like we had our own place.
The apartment is within walking distance of the beach, Lands End, and the West end of Golden Gate park, which was great. There is also a nearby Walgreens and Safeway. However, there wasn't much else in the area. The closest bus is the 38, which seemed to be a major route and we were able to access a lot of great locations this way; just keep in mind that it took anywhere from 40-90 minutes by bus to get to most places.
Chani was a good host. Although we never met her in person, she was very responsive when we had any questions. And when we didn't have any dish soap, she left a new bottle outside our door upon request.
The apartment suited three adult women just fine. The couch is actually pretty comfortable!
