Lois's place was great for a grad student with summer internship in downtown San Francisco.
The room is large and has a full private bathroom. It contains a large bed, a space heater, a wardrobe, a chair, a desk, a table, a nightstand, a shoe rack, and a luggage rack. All of the furnishings are cheap, but they worked fine. The best parts of the room were the large window (from which you can see a sliver of the Pacific) and the full bathroom (which is cleaned once every two weeks).
The kitchen is shared with other guests and is not particularly clean. If you plan on cooking, you may want to bring your own dish soap, dishwasher detergent, cookingware, dishware, etc.
Also, note that you share the floor with three other private Air BnB rooms. For most of my stay, my fellow guests were quiet and kept to themselves. But the walls are very thin. So you may hear what's going on in your flatmates' rooms and vice versa.
If you are commuting to downtown SF, there is a muni stop less than a block away at 19th & Taraval. I commuted to Embarcadero every day, and it was probably 50-55 minutes from door to door.
There aren't a ton of restaurants in the area, but having a Safeway across the street was better for physical and financial health.
