Tired of clouds? Which San Francisco neighborhood has the sunniest weather? 632 Shotwell at 20th Street is arguably the suniest spot in the entire City. This 1,152 sqft (measured to INTERIOR) top-floor, full-floor 2-bedroom flat with 2 private decks, in-unit W/D, and parking is on a permanent slow street. No through traffic at all. Full barricade. The house next door just sold for $1M above the $3.8M asking price! So you’re in very good company here.
