Ivan and Wendy were wonderfully responsive to my questions both before and during (and even after!) my trip to San Francisco, and they were extraordinarily welcoming the whole time. On more than one occasion, they interrupted or delayed their own plans in order to give me informal advice about their San Francisco neighborhood and to help guide me through the city. Their home is an oasis of calm in a bustling neighborhood, with a beautiful, verdant yard just outside their sun porch, which is where I spent most of my time enjoying the natural light and the sight of the lemon trees outside their window. I highly recommend their house.
