This was my second stay with Ponge. The room is as described: private, comfortable, clean, plenty of space. There are windows for light and ventilation, and there is a very efficient heating system. The kitchen and other common areas are welcoming and easily shared.
The vibrant neighborhood has parks and playgrounds, restaurants and stores and bars, coffee shops, a lovely grocery store, a Catholic Church and a public library.
Ponge is easy going, easy to talk with, and always pleasant.
Whatever you are doing in San Francisco, this is a wonderful location for your stay.
