This place is... exhale... beautiful
The Westin on Bund is located right in the city center, so needless to say, the BEST location.
Lets start with the rooms. OK the bed is amazing, there is a special name for it but I cant remember what it is. When you get in, you won't want to get out. Except maybe to check out the also AMAZING bathroom. it's like a tropical rainshower and tehre's a glass next to the tub so you can see the entire room. The decor is really exquisite and to the finest detail.
Whenever I got back into my room, the TV would be turned on to give it a homey feel instead of a sterile feel which I realy really liked.
The Westin also probably has the best buffet spread I've seen in Asia.
If you're willing to pay the big bucks (someone else paid in my case), spoil yourself at the Westin. I just got a really good vibe about this place.
