I stayed here while attending a conference at San Francisco State University and it worked great for my home-base. It was about a 15 minute walk to the campus, and about 25 or 30 to the specific university building within the campus I was going to. A lot of the walk is around Lake Merced which made for really lovely views, actually, and the few times I walked home past sunset I didn't feel unsafe. It's quite close to a supermarket as well, which was handy. It was clean and had everything I needed for my four-night stay. The hosts were quick to respond and flexible with check-in which I really appreciated. The only small downside I found was that the walls were quite thin, so I would recommend bringing earplugs if you are a light sleeper - I didn't hear anything the first night but I think it was another guest a couple days in who talked quite loudly on the phone. However it's a great choice for an affordable option in San Francisco, seems well connected with public transport, and is really ideal if you want something close to San Francisco State University.
