Elmer's apartment is located on the edge of Castro and Lower Haight, meaning it's well suited to reach some main parts of the city. The apartment was super clean, stylish, kitchen was well equipped and the breakfast counter was plentiful. We definitely felt like at home in his home. Also Elmer and his dog London are both very friendly.
Very highly recommend this place to everybody who wants to explore San Francisco. As the apartment is so centrally located, public transport is well catered for and a car would not be necessary (even though we had one and parking was never an issue).
