Highly recommended.
While the listing classifies this stay as a private room, it's basically a private apartment, with its own locking door, bathroom, and super cute kitchen. The place is located near all the excitement of Mission, but still lives on a clean and safe-feeling side street that's appropriately tucked away. There are tons of places to eat nearby, with a great brunch place, coffee shop and fancy bodega for late-night snacking all within a single block.
The room itself is clean, tidy, and neatly furnished, with loving touches such as a detailed "how to make coffee" guide and off-the-beaten-path walking guides of the city.
This is a great little place from which to explore the city. I didn't need a car, with busses and the bart a short walking distance away. If you enjoy being on foot, the Dolores park is about 10 minutes away, Castro about half hour, and Mission just two blocks down the street.
