Took a while to find as entrance actually on Shantung St off the corner of Sai YeungnChoi St, right next to the Sharetea. In the heart of Mongkok so very convenient. Was able to check in at 11pm by ringing the caretaker at the desk even though it says after hours check-in is not available. I speak Cantonese so he was very helpful & showed me everything, to my room and how to use everything. There were extra bathroom items at the desk. Place is tiny especially as expected for this price in HK, everything you need tho: self-contained private bath with shower over the toilet, hair dryer towels, small TV, chair, hangers etc but must temper expectations in terms of cleanliness & livability. I ran the aircon all night and the floor was wet from the precipitation, everything a bit damp and will get moldy after a couple of days, smelled of smoke all the time & more difficult to navigate usage of bathroom due to size etc
I'm just one guy traveling by myself so it was ok and only stayed one night, prob wouldn't stay too much more.
