What a great hotel. I haven't been to the Landmark Mandarin but I can't imagine they can beat that simply for the reason of the spectacular views you get both on harbor as well as island side.
Flawless design. Huge rooms (smallest starts at 730square feet) Professional and kind staff. A bathroom that is hard to beat.
If you need a pool or a spa this is not your place. If you want to be treated like a king by the friendliest staff and spend hours just looking over the Hong Kong skyline in the softest bathrobes you ever got provided by a hotel. This is for you.
