This place very accessible - as the Tsim Sha Tsui MTR station is literally right next to the building. Big tip: Use the air-conditined MTR pathways to get to one part of TST to the next. Perfect for avoiding the heat/humidity as long as you can.
The room is tiny, but that's to be expected in Hong Kong. Despite that, it's still comfortable and I was able to move around with ease. There's not much foot traffic going to the room and the wait in the elevator isn't too long. The housekeeper always makes sure the room was clean. They also provide drinking water which is very handy during the hot humid days.
I recommend this place.
