I spent few days at Nancy's while on a business trip in San Fran, and all I can say is that I had an amazing experience, and that I will definitely come back. I especially enjoyed Santa's company - she's the sweetest, most adorable doggie, and she definitely cheered me up when coming back home after a long day at work. Both Nancy and Santa are friendly, but at the same time very respectful of your space and privacy, so the interaction with them went super smoothly. The location is great, close to a lot of cute restaurants, cafes, and bars, and very close to the Mission. I would absolutely recommend this stay to anybody, especially solo travellers like myself!
