Sacramento Street between Divisadero St. and Presidio Ave. is mostly a quiet neighborhood. There is the public library which is small but is a nice, quiet place to work. There is also a few boutiques and cafes, my favorite café being Café Luna which is a little pass Presidio Ave. There is also a small, nice theatre called the Vogue which shows one or two new movies for a reasonable price. There is also SF University High School which has a building so there will be occasionally a flock of students walking to and from class. Nearby bus lines include the 43 Masonic, 1 California, 2 Clement, 3 Jackson, and 4 Sutter so it is a very convenient spot for buses.
