The pros: The location is good, the staff is quite friendly for Hong Kong and very helpful, the place is very clean. Overall I believe the price to the size, location, cleanliness is quite excellent and would recommend. Oh, and the rooms are super quiet, you can hardly hear neighbours (even noisy ones) or street noise, which is unusual in Hong Kong. The gym is small but good, and they have a small shared laundry room/kitchen.
The cons: the breakfast is just some bread I guess (but coffee is OK), the outdoor deck was "closed for overhead construction" the entire 2.5 weeks I was there, the shower can be quite slippery (but they do have a mat). Lastly the bed is quite hard which is not great for side sleepers, but it is no harder than all other hotels in similar price range, i checked.
As said, I would definitely recommend it.
