Potrero Hill is one of the sunniest neighborhoods in San Francisco, located on the eastern side of the peninsula and flanked by the San Francisco Bay. It is insulated from the fog and chill of the Pacific Ocean that is typical on the western side of the city. It is a residential neighborhood and not considered a tourist destination. Although it is not the most walkable neighborhood in San Francisco due to its hills, it is generally considered a very convenient location due to its proximity to offices, shopping, dining, entertainment, freeways and a Caltrain station. Despite being surrounded by busy neighborhoods, and featuring a thriving commercial area on 18th St., Potrero Hill is generally quiet and sleepy. According to Google Earth the highest point is near the intersection of Carolina and 22nd streets at 320 feet above sea level and close to the center of the neighborhood.
