I've got budget to visit hk for one night, it is really good deal compare to the value and location. Causeway bay is the busiest shopping area in Hong Kong. I've been to this hostel twice, they improve hygiene but the receptionists are rude, didn't seem like welcome you at all, other employees were nice.
I couldn't sleep I think it's because of the bed, my nose kept running the whole night that I knew the bed sheets weren't clean.
I've in a Dorm with three beds, one roommate was really loud eating and looking for stuff till 3am it is really annoying. but that's what you get when you booked a dorm.
