Annria was a very good host - easy to communicate with, easy check-in, very clean accommodations. It's about a 15-minute walk to the Bart station, which will get you into downtown SF - or you might want to take the time to figure out the bus route, which was about 2 blocks away. Another review had mentioned that there was no way by which to lock the apartment door, but we didn't find it to be an issue and the building itself is quite secure.
