It is a hostel but it was not backpacker vibes at all. Not social. There are only a few bathrooms for quite a lot of people and they are also quite faraway from some rooms which is when you need to go during the night. Also, the blinds on the beds are very loud.
However, the bed itself is quite comfy and the room has great AC. Also, it is perfectly located to explore Singapore. If you are here for a couple nights, not looking to socialise, and want to be close to things, I recommend. But I would not recommend to your typical backpacker who might be looking for some atmosphere
