This was by far one of the most affordable options in San Francisco. Valeria is a wonderful host - very helpful and responsive. Keep in mind that this is a basement apt, so it is not meant for tall people (this did not apply to me, since I'm only 5'2"). There's no TV or cell service in this apt and the WiFi was mostly reliable - plan to be out and about while staying here. There are several affordable restaurants within walking distance. The area has a quiet, residential feel and appeared to be very safe (which was nice as a solo female traveler).
