Kei's apartment is in a great location and very, very clean. The guest room has an aircon which works great. The space is very small; however, that is typical in Hong Kong. Additionally, you shower practically on top of the toilet- I mention this to set expectations, not as a negative thing. Real estate in HK is incredibly expensive so this is a very normal thing and Kei keeps his place very clean.
The apartment is off of a busy street so at night it's fairly loud with street traffic, but Kei provides ear plugs!
I would stay here again!
