We had a great stay - the location of the flat is perfect for exploring the city, and has absolutely brilliant views of the area. Potrero Hill is a phenomenal area, with great restaurants, cafes, and is even very close to Anchor Brewery for some local beer! The flat itself is spacious, clean and comfortable, although I'd recommend packing a jumper for the evenings and mornings (San Fran gets cold!). Overall, a brilliant stay, and highly recommended.
