This place is clean, has a good lock on the door, is close to the Mong Kok MTR station and the bed is thin but comfortable.
The biggest issue is that the shower and toilet are usable with difficulty due to plumbing issues. I just used toilets at restos/malls. I had a room with windows so it got noisy.
For the price, I feel like I got my money's worth. I would recommend this place if you need a quick stay. I would also recommend washing yourself with soap and a wet cloth instead of using the shower.
