Katherine was a great host. She was very responsive and helpful with all of our questions, especially in dealing with administrative issues that arose due to a change in ownership. The flat itself was perfect for our needs, especially since we were travelling with a 7 month old: there is only one step to enter the place (not easy to find in SF!) and a play pen available. The flat was clean, modern and very comfortable - a great oasis in the city on a street with some beautiful old Victorians. The location was perfect for us too: there is easy access to public transit to see the city, and a lot of great things are within walking distance, including some great restaurants and coffee shops. We stayed for a week and would stay again in a heartbeat.
