Kymberli’s place is lovely - nice and open, light, airy and clean, and nicely decorated and furnished too. The kitchen is well stocked, and she cooked a great steak one night that she let me snaffle some of.
Kymberli is super-friendly too. Communication through my stay was great, and she was full of tips and advice for cool places to go/things to do/stuff to eat. She let me leave my luggage there until my flight on the last day of my stay, which was really convenient.
The location is good. It's not exactly central, but it's a lot cheaper than staying in the centre and it's only a couple of dollars for a taxi/train ride anywhere. Walking into town is possible but it's pretty industrial scenery for the most part.
This was my first time with AirBnB, but I'd definitely stay here again if I'm ever back in SF.
