The Great Wall Sheraton is really in need of a refurbishment. On the bright side the rates are good value. Its not that my stays have been awful, in fact I have been looked after pretty well, its just that it could be a lot better hardware wise.
I would say the ROS is similar, don't know on what basis it got a category bump last year but it could really do with a refurb and treatment of plats more in line with the other BKK properties.
