I have to agree with
CPH-Flyer.The photos that look the most similar are the 3 EDITION properties in Asia so that's not surprising that there would be more commonality between them.
West Hollywood and the late Times Square are distinctly different in their furniture and decor choices and the photo of the NY Edition looks very different from all the other photos.
I do get what you mean though. Compared to some other brands like StR and RC, there is more of a common design thread between the EDITION properties.
