Jimmy's place is superclean, rooms are spacious, and good value for money considering the prices in san fran. Of course, it's a ways away from the city center but the connection with the metro is 5 minutes walk, and a straight shot into town. Fully equipped kitchen too if you want to cook your own meals, or alternatively there's a few good coffee shops and restaurants walking distance. Plus if you're into it, there's a really cool surfboard maker who builds boards out of wood and recycled foam, called Wood Shop.
