Annie's place was just perfect for us. It was just outside of downtown and just a block away from a bus stop that takes you into downtown. You can also go to the nearest BART station at Balboa Park and take the metro. In that way you'll be in downtown in no time.
When we arrived, Annie gave us a very warm welcome and she gave us a good tour of the place. This place was VERY clean. We have done 5 airBNB's at this moment and this one was super clean. One downside was that the walls are pretty thin so sometimes you can hear Annie's family but at night it was very calm and we had a good night sleep.
Oh yeah and the internet is super fast :-)
