Stayed at Evergreen Hotel before.
Take A21 from airport and drop along Nathan Road at stop no 10. Hotel is about 3-5 min walk away. I got a triple room on the 4th level and it is quiet at night. There is a window but it is locked. Although room is small with beds and space just enough for 3 persons, it is cleaned thoroughly everyday. There is a LCD TV which has many international channels plus the other local Hong Kong channels.
Even if you book a standard room, you add extra bed is abt 30sgd ...
