I booked this for a week while looking for a permanent residence and it was perfectly fine. The best thing about this place were Wilson (host) and his brother, who were constantly available via WhatsApp etc. after hours to answer any questions I had.
The room is just as advertised, the bathroom is actually a bit bigger than expected, the bed alright, air condition worked, the TV I didn't try out. I stayed here by myself, for two people with a lot of luggage this would be a bit cramped, since there is no closet. But there is rooms with bunk beds, too, so this might be better suited. It's right in Tsim Sha Tsui and not too hard to find and for Hong Kong quite good value for money. If there is a tiny thing that can be criticized it is that when neighbors use their water appliances this is a bit loud, but on the other hand the air condition is really quiet. Anyways, nothing the hosts could do anything about.
Overall I would definitely recommend this and come back! Communication with the host worked great!
