One very rude and insensitive...

Liked: Lady who greeted me during check-in was very helpful.Cheap i guess
Disliked: Room smelled really bad when I first arrivedToilets can get pretty dirtyBeds aren't the most comfortableRooms are really small, not much space to put luggage if your'e travelling with more than one bagLocation isn't great, lots of homeless druggies along the street outside the hostelAll this was OK by me, given the low price. However, my check-out experience was the last straw.The Indian clerk who managed check outs was extremely unpleasant. I returned to the hostel after a morning out past check out time (10.40am) as I got into an accident outside. I explained this to him when i returned and said I still needed a shower and to pack my bags. 30 minutes later he comes knocking on my door aggressiveky warning me that I overstayed, which i was fully aware of already and trying my best to pack as fast as possible (I explained my sense of urgency to him). BTW, this is 4 hours before any other guests can check in (check in time is 3pm). He continued to threaten to call the cops on me even though I showed him that I was clearly trying my best to pack all my bags. This made the whole stay extremely unpleasant... Clearly I was not purposely trying to linger around and kill time (in fact I was trying to get my ass out of there) so there was really no need to be so rude. Didn't return the 20USD deposit due to my late check out (fine), but the rudeness was really really unnecessary. Dude even kept chasing me out of the common area after I had checked out, while I was clearly struggling with my bags.

Got my money's worth.

Liked: I had decent sleep for five nights. Staff were mostly friendly and helpful. Close to everything: restaurants, stores, buses and other public transits, though the neighborhood itself is rather downscale within a few blocks.
Disliked: There should be more bathrooms. Kitchen is unusable unless you bring your own cookware. But this is San Francisco, and a decent place to stay for the price of a pizza! Can't have complaints.
