Like all the others here, we were not disappointed by Catherine's airbnb. It is a truly beautiful place. We especially appretiated the little details such as shampoo, cotton swabs or the little sweets. Communication was not a problem and early check-in was also possible. We never met Catherine in person, but her husband showed us the place and he was very welcoming and friendly.
Going in to san francisco using Bart was also very convenient. We would stay at Catherine's again and can recommend staying with her!
