It's clean and very basic - although it meets all the basic needs, I didn't find any reason to return here or recommend it to others, apart from the price.
The rooftop bar was quiet and the service terrible when we were there. Wifi wasn't working, food was really bad. Not the friendly backpackers experience I'm used to.
But the showers are hot and the sheets are clean, so for US$20 for a private room, it's a good option in this price bracket.
