Staying here right now. Had booked a business deluxe room and received room on 12th floor which is underwhelming. Very dated decor. Do not think this was an upgrade (in fact am wondering if its not a downgrade...). All sorts of suites available on spg.com but oh well...I am just too tired of having to negotiate for this.
Staff is very curteous though, and butler swiftly arrived with sparkling wine (this is definitely not Champagne) and orange juice. Towers Club is OK with decent snacks in the evening and one free alcoholic drink. It is a bit oddly lighted though, very bright, which does not make it comfortable.
Overall not a bad experience but would probably choose a hotel that is in better shape next time in MEX.
