If I could rate this hotel less than terrible I would.
I rad some reviews on this hotel before I booked and it seemed to be a fairly even split with some people saying good and some bad, so i thought I would give it a try seeing as it had a great central location for the price. I now wish I had paid the extra to stay elsewhere! Triton across the street was $200.00 extra for three nights, should have gone for that! 
As soon as we walked into the hotel we all reallised that the Lobby smelled of a musty urine smell, we thought this may be coming from outside drains so didnt think too much of it.
We entered the lift which was extremely old and rickety, only three people to ride at a time, it only just made it to th fourth floor with our luggage! 
When exiting the lift we realised the upper floors also smelled of urine including our room.
The door to our room just didnt feel secure and at night the corridor lighting shone through the gaps around the frame!
There is no air con in the room so be aware if you need it to be cool in your room while you sleep you wil have to leave your windows open and the streets below are incredibly noisy.
The room looked like it had not been cleaned for a very long time, the sheets seemed to be clean but we had stains on our towels, dirt on windowsills, bath, sink, sideboard, carpet ( chewing gum!) filthy blinds. We actually cleaned our room ourselves with cleaning materials and air fresheners from the CVS on Market.
The Hotel does offer discounted parking but not at the car park right across the street?
Not many TV channels or screens over the windows, we were bitten many times by mosquito's.
If you are looking for a San Fran hotel on a budget dont make the same mistake as us by staying at the Astoria,pay a little extra and stay somewhere else, it didnt spoil our San Fran stay but certainly didnt add to it!
