Sebastian was a wonderful host, going far out of her way to make us comfortable. The apartment was sparkling clean and beautifully appointed. Small things like fluffy towels and lavender soap reflected her attention to detail and her excellent taste. There are absolutely no negatives to report about Sebastian and the apartment; in fact, she has created an oasis of luxury, tranquility, and warmth In the Potrero Hill neighborhood. For those unfamiliar with San Francisco, however, as we were, I will note that the streets are extremely steep in that area. So those with any mobility issues should be prepared to Rent-A-Car or take cabs (actually, we recommend Uber, not cabs!).
