Ponge has a beautiful house in a quiet neighborhood south of downtown. The ride into downtown is $15 with Uber and $25 to the airport. We got the whole basement to ourselves incl. our own bathroom, which was awesome!
The room has a great size and everything you need and Ponge left plenty of towels and water for our arrival.
However, the wifi does not work in or near the basement, which meant that we had to stay upstairs in the kitchen to be online. This was obviously not ideal as it left no room for privacy.
Ponge is a really friendly guy with lots of tips for how to get around San Francisco. He is very interactive, and likes to befriend his guests, which is great. however, if you are only looking for a place to stay, this is probably not the ideal place for you.
