I just came back from a 7 night stay, and although the artwork is a bit quirky, it does not get in the way of anything. I like the hotel. I like the location, getting around was fairly easy, although we do tend to use UBER and taxis. We also walked to quite a few places from the hotel.
Lounge is good, food is a bit repetitive and a bit lower quality than what I would expect of a JW. My point of comparison is always the JW Bangkok. Although JW Hong Kong is nice, I prefer Bangkok. This JW is good, just not over the top good.
Under cooked bacon in the mornings, the same three sandwich offerings at tea every day, barely passable scones, etc. Rooms are very nice size and functional. Bed was very comfortable.
