Our family (four adults) stayed here for a long weekend. Amal and Charlie were great hosts - good communication and flexible with accommodating our late check-in time. They left some English muffins and drinks as a welcome gift, which was a thoughtful touch.
The unit is exactly as described (two generous bedrooms and bathrooms), the beds are comfortable, and the space gets decent sunlight for a basement unit - overall a very nice home base to start and end our days.
We were visiting someone living in the neighborhood, so the location worked very well for us. It was, however, a bit farther from downtown San Francisco than I had imagined when looking at the map beforehand. Cabs took about a half hour to get downtown, which was not a problem, but something to be aware of if you are planning to spend most of your time there. The Outer Sunset neighborhood itself is nice - quiet, residential, with some great coffee shops/restaurants within a 15-20 minute walk from the unit.
Thanks for a great stay!
