My mother and I stayed for 2 days at Ponge's place. Ponge is a very nice guy. His hospitality and responsiveness are amazing. His house is very lovely and clean. The room we had was spacious and it had its own bathroom. The neighborhood is awesome with so many good cafes, grocery stores and restaurants. You can easily take bus or Uber to go anywhere at SF with a fair price. Overall, I would highly recommend Ponge's place.
