Ponge was the nicest host ever! I can fully recommend staying in his place. You have your private room and bathroom. And you can do the laundry, use his fully equipped kitchen and watch tv in his living room. Actually, we were always watching baseball together. Thanks to Ponge I now know the rules!
I so much enjoyed relaxing on his patio. When the cold wind is blowing in SF you can be sure that on his terrace it is protected and really warm.
Also the neighborhood is really nice. It's safe and Cortland Ave offers some nice Cafes, Bars and Restaurants. A grocery store is close and also Safeway is not far away. In a 5 minutes walk you can enjoy an amazing view over the whole city from Bernal Heights park. Transport connection is also good. Bus 24 stops really close.
All in all I really liked our stay with Ponge. Me and Jirka moved to SF for work. We lived in Ponges room for 1 month and even extended our stay as we couldn't find a flat in SF immediately.
Conclusion: clean, nice, everything you need available, good neighborhood. Absolutely recommendable!
