There are two biggest selling points of this place:
a) the price: among the lowest in the Sham Shui Po area
b) the location: less than 500 meters walk to the train station and the Sham Shui Po flea market walking street area
The owner is responsive, offers good instructions to aid us finding the location, and kind enough to allow us to check in earlier when the previous guests checked out before 12 PM. You can find shampoo, shower gel, etc. in the bathroom. There is a fridge that's functioning. WiFi is also working. There is a small convenient store at the back of the building, we liked to buy drinking water from the nice and friendly man before going back up to the room.
Other than that, the place has little else.While the room is basically clean, we felt it quite damp, maybe because there is no window at all. The toilet too while being clean, yet we felt it is a bit run down. A bit of renovation might help. The building in which the room is situated is quite old, and the environment feels gloomy. People who are prone to depression should think twice. Also, during booking, we did not see photos of the whole room and the rest of the building, what was shown was just cropped photos that only show what is presentable.
If cost is your major concern, then this might be a good choice.
