It seems at this hotel some floors have been fully refurbished/rennovated recently (however I think it's only the top floors like 7 and 8) and other floors (floor 6 and below) remain in the old 1980s style decor. However, I didn't see all the floors so maybe a few other floors have been refurbished too.
The refurbished/rennovated rooms are sold as "superior", "deluxe" and "executive".
