I had a fabulous time at Esther's place. Although it's not in the city itself, there are good transport connections that, combined with the walk to her place, can get you into the heart of San Francisco in under 30 minutes. The apartment is a little small but more than enough space for one person, and the provision of amenities such as tea/coffee, shampoo, and shower gel, as well as facilities like a toaster and a microwave, make it very liveable. Esther herself is extremely friendly and generous, and I enjoyed chatting with her. This place is a gem.
