Minus: no space in the rooms (you can hardly turn around without your backpack on) plus the bathroom/toilet combos (tiny, wet, hot and humid as no AC). Mattress old blus trey and rails you see in the pictures missing or broken.
Worst: lacking service and friendliness of typical hostels. No one can or wants to help with sightseeing information, all power outlets are typical Singaporean ones (easy to make multi type or USB outlets) and they won’t even help you out with a quick charging. Instead they want to sell you adaptors for a few dollars. What a waste of money and bad for the environment as these adaptors get thrown away after most people move on after 1 or 2 nights. You won’t need them anywhere around and in hardly any other country. A little bit more service orientation could help.
