If you require good sleep or maximum comfort, you must consider this hotel carefully, their rooms have no soundproof windows at all. Since this hotel is located in downtown area, sirens are all over the streets. My room was on 25/F and all windows were all closed, but sirens were really really loud even those police vehicles or ambulances were like 10 blocks away, it actually is my worst sleep ever during traveling in my life. If you are long haul travellers, definitely it's not helping for jet-lag. The room is big, but the wifi signal coverage is very weak, the wifi cannot reach the devices when I was in bedroom or bathroom, so if you are business travellers and require internet for online meetings, you may really think about it. The hotel only provide 2 bottles of water at all while my stay was 4 nights, when I requested extra, they charged, I am not sure if this is whether environmental policy to restrict or what, but you the room rate is at certain level but I was surprised it cannot cover a few more bottles (like 2 bottle each day). I rarely make a written review, but honsetly, I didn't enjoy my stay very much this time.
