The pool is a strong point, one of the best in HKG. Full sun, not shadowed by nearby buildings -- an advantage being high in Mong Kok vs. the island
No noise from the street. Never more than 3 or 4 guests when I've used the pool on a dozen occasions. I'd rate it one of the best hotel pools in the world, given the view and lack of crowding (of course that can easily change given the number of rooms).
