He responded promptly whenever I send him a message on Airbnb. But I recommend to add his phone number to sync his Whatsapp so that you can call him without local calls in case he is not responding on Airbnb (It did happen to me when I was checking in, but it was not a big issue as I waited only ten minutes or so). You might be surprised by the size of the room being smaller than you expect. But the room was prepared with all you need and it is not at all small once you have got used to it and know how to make a use of the room. The location is just nice to get to any attraction in HK. I have read here some previous visitors complaining about the noise or smell but me and my gf didn’t feel any issue for them. Only one downside of this room was the key holder not being smooth to open.
