The room is fine, the service and the communication of this apartment manager is good.
But this room is of service apartment operated by another company.
Then I found that the room price in this page is almost twice as the market price in the same area with the agency fee. (if you can pay this price, you can rent better apartment in the same area.)
If you want to skip the communication with service apartment (ex. contract), I recommend to use here.
But if no, it might be better to try to check the information of service apartment in Hong Kong before making decision.
