Went there a few days ago. The nearest station is Yau Ma Tei. I'd say the walk from hotel to the station is around 15 minutes. The way to the entrance is an uphill but manageable. The landmark is the gasoline station in the corner of waterloo and another road.
The room is very clean and simple. They have very good room service. There's wifi at the lobby but there's none in the rooms. But anyway, it doesn't matter so much since I just went there to sleep after a long day of tour.
I stayed for 3 nights and they charged me 2,100 HKD plus 200 HKD deposit which they will return when you check out.More
