The host's studio is in a very modern service apartment building, so it has standard 24 hour doorman, access card for elevators and room. The studio is very airy with windows on three sides. I ended up opening the windows instead of using the air conditioner. The street noise is very acceptable as the studio is on higher floor.
In compare with any hotel in HK, I appreciated this place a lot in terms of:
1) It has a kitchen (not that you would use it as getting food is so convenient in HK)
2) The studio is tad bigger than most comparable hotel rooms.
3) No carpet smell
4) You won't hear the baby crying next door like in a hotel room.
5) Had I said that you could open the windows.
Sure I would stay here the next time I visit HK again.
