Guillermo's residence is a convenient spot located in the heart of my favorite neighborhood in San Francisco. It is walking distance to tons of restaurants, cafes, and public transit. Check-in was also super easy. I stayed in the Drum Room which was large and spacious. The internet was strong enough for me to work off of which I always find super important in a listing. More than one room is rented out so make sure you are comfortable with a somewhat hostel-like or communal living experience before booking. But I think Guillermo has been very honest in his description of the rental so hopefully my writing that isn't a surprise. Plus you CANNOT beat the price. I don't think there is a more affordable place to stay in the city. I'll definitely book again if I need an AirBnb in SF.
