We stayed here for 5 nights. The best thing about the hostel is the central location, Boat Quay is a cheaper area for casual bars and happy hour drinks and it's an easy walk to 3 MRT stations to hop around the city. The reception was really friendly, there's cheap towel hire and soap dispensers in the showers. Laundry is expensive at $12, but there's a dryer too.
The bed was comfortable, great quality pillows and two international adapted plug sockets each. Good noise cancelling in the rooms, couldn't hear a thing from the bars downstairs. High speed WiFi everywhere.
The issues we did have were more bad luck, my boyfriend's flip flops were stolen in the hallway, there's a no shoe policy for all the rooms so you have to leave them there. We were told no CCTV in the hallway so nothing they could do.
We also had an older couple stay opposite our capsule for 3 nights who were very sick, unfortunately they did not practice good hygiene at all (talking coughing all night not covering their mouth, spitting what came up into cups in bed, gargling mouthwash in bed). There's no windows in the rooms so it just felt like this germy air was being circulated around the room.
But like I said, bad luck, enjoyed everything else about this hostel and had an amazing time seeing Singapore staying here. Plus they let us store our luggage all day after check out and take a shower before heading off to our flight, so I would recommend this place for sure :)
