As a guest of Check Inn HK - Hostel, you'll find a library, an arcade/game room, and multilingual staff. A computer station is on site and WiFi is free in public spaces. Check Inn HK - Hostel also features tour/ticket assistance, coffee/tea in a common area, and laundry facilities.
I gave it two stars because overall it is nice, but it is really unacceptable when at 03:10am in the middle of the night, the night manager of the hostel goes into the dorm room, switches on the light and even then when you comment that it's 03:00 am and you want to sleep and normal people would use a flashlight, the only response is "he needs to check in" - pointing at a guest coming in. The guest was happy to use the flashlight - for the manager to switch on the light in a dorm room at 03:00 am with literally 7 people sleeping, without any curtains, is unacceptable.
The dorm rooms were cleaned every day. The bathroom was also cleaned and toilet paper was always available. It was also to meet and make friends with the other travelers and some of the long-term guests.
