Just found a pretty good review of the hotel on a new website that reviews hotels and takes A LOT of picture. Thought it might be of interest:

Obviously not SPG member oriented, nothing on upgrades and such, but the pics are great and I like the overall look of the website.

Hopefully will be able to stay at the W Sobe sometime this year!
