Overpriced but nice enough
We left booking accommodation in San Francisco too late and this was the only place we could find for the lowest possible price (although not that low) that had ok reviews. 
Having been staying in hostels/motels for 3 months, I thought this place was fine and just what we needed. Obviously for the price you are paying, it is not really worth it - but it was the cheapest place we could find.
Saying that, I found that the building itself was nice and the room was fine. Ok, it was a little outdated looking with the patterned wallpaper and carpet - but it was a fine size, it was clean and just what we needed. We stayed there for 3 nights.
Breakfast wasn't great, but was what I was used to from staying in hostels/motels. Coffee/tea, orange juice, toast and hard boiled eggs. There is a little area where you can eat your breakfast which is nice, or there are trays to take it to your room. I did think it was a bit weird though that they don't provide any cutlery or plates - there is only a knife to spread your toast so you end up eating your toast off a napkin. For the room rate and basic breakfast, I think they could at least give you a plate and cutlery!
The location was good for us as its near a bus stop that will take you to all the other main areas/to another stop for a connection elsewhere.
I found the reception staff to be very friendly and helpful - both the lady and man who worked during the day/evening. They let us leave our bags there all day and organised a shuttle bus for us to the airport which made life a lot easier as we had a late flight.
I would recommend booking accommodation in SF early to get somewhere for a decent price, but this place is fine enough if you can't find anything cheaper.
