About the location:
This place is infested with people trying to sell you food and rooms. Gets annoying after a few visits.
This building has at least 5 blocks (A-E) each with two elevators (even vs odd floors). They are almost always full and you will have to wait in queue to get to one of them. Also if you are on one of the lower floors, you might have to wait a very long time because the tiny elevators are full to get you.
Careful if you decide to use the stair, I twisted my foot climbing down the extremely tiny stairs.
About Singapore Hostel,
For new year's eve the owners were offered more money than my booking and they gave away our room. Each night we had a different room, both rented by them from another hostel in the same building.
The shower head is right over the commode and they claim this is because of Hong Kong rules, this is not the case.
