The space is quite small, as all places in Hong Kong are if you don't pay the premium. It is a little cramped for 2 people but for one person it would be perfect! The room is very clean and just a few steps from the MTR. It's also very easy to take the bus to and from the airport at this location.
Mei is fantastic and answers all of your messages very quickly if you have any questions. She's very accommodating and does her best to make your stay pleasant.
