Location, location, location! You could not ask for a better place to be in San Francisco for the price. A few blocks to countless restaurants, one block to a wonderful dog (and people) park, just a few blocks to a parking garage.
Because this is set back off the street, it is not noisy at all. Very private, yet accessible to so much. The owner is responsive, so that's a big plus, as is the very comfortable bed.
Only downsides were that it could have been cleaner, the landlord is right above you, there is another airbnb guest right next door and the walls are thin, and it is not as big as it looks in the photos. It's the size of a motel room, although does have all the amenities.
All in all, a great place to stay while in the city by the bay.
