Our 9-day stay at Sarah's was fantastic! The studio was immaculate, fully equipped, and a short walk to small groceries, cafes, and Whole Foods. The bed was REALLY comfortable, the shower was terrific and overall the space was very pleasant and inviting. Sarah lives upstairs so we ran into her a few times, and she was exceedingly responsive to texts and available if/when needed.
Potrero Hill is a terrific residential neighborhood, close to Dogpatch and the Mission for great eating, and an easy Uber/Lyft to other parts of the city. I enjoyed long walks every morning--lots of hilly ups-and-downs, gorgeous views in all directions, and interesting houses to look at.
We really look forward to staying in Sarah's studio during future visits to SF!
