Lake Street, San Francisco

"This is one of the best neighborhoods in the City, if the the Bay. It is safe, friendly and full of beautiful homes." People who live here love it here. While this neighborhood is further removed from the central core of the City it still has a tight-knit feel. The streets feel broader and wider with a large numbers of 2-unit buildings that are either condos or income properties; large apartment buildings, most with garages on the street level. As you get closer to the Presidio and to Land’s End you’ll find some large, if not stunning houses. Most structures here are stucco and older and you’ll find the occasional TIC units.
