This was a perfect spot for our quick stay in San Fran. The room was impeccably clean with its own private bathroom, and slippers, robes, and other amenities provided. The rooms each have their own code so you have privacy and security. Only negative was the wifi didn't work (discussed with other guests and host restarting router didn't work), but we didn't need it for our stay since we were out every day. Just something to note if that's important for your stay.
Airbnb is just a couple blocks from the beach, great location. Its a bit far from some of the main touristy attractions, but public transportation works great if you don't have a car (and bus drops you right by the apartment).
