On our cold and rainy California trip across the state (and staying at 4 airbnbs), Robert and Kristy's was the warmest and coziest, with all the amenities we needed. The neighbourhood felt safe and comfortable. I just wish their home was a little closer to main areas of SD but all it took was a 15-20 min Uber to get where we needed, and we had a rental car, which I would reccomend!
