David was super quick to respond to texts, and that was really helpful. The location is in such a quiet neighborhood and we felt perfectly safe if our teens left the house without us. We loved being near Clement (just a few blocks) with its many restaurants and shops when we weren't exploring deeper into the city. And it is so close to the U. of San Francisco campus. It was a great base for spending time in the city and easy to get around by bus and Uber.
