We had 4 guys in our group and were very comfortable. Master bed is largest, and has its own toilet/shower. 2nd room is pretty large with two double beds and a window, and 3rd room is more the typical HK style. There's a second bathroom/shower just off the main living area. AC in every room, solid wifi speeds (even with ~dozen devices between the 4 of us...), and a nice charging station next to the smart TV. We also plugged in a Chromecast and we're able to watch whatever we wanted.
Location would be almost impossible to beat if you're wanting to stay in TST, as it's only about 50 yards south from TST A1 on Nathan. Closest convenience store (Seven) is right outside the back door on Lock.
Well kept space, exactly as described and Phoebe was incredibly responsive with check-in and a couple of requests we made.
The Shanghai buns from the shop next to the elevator are definitely worth trying.
Speaking of... it's a very large building. Elevator can be a bit of a wait during peak times.
I would absolutely stay here again!
