So for anyone wondering the nightly rack rate at the Mystique its 790EU, as even though I cancelled within window they charged me 3950EUR anyway on my on-file Amex, even though it was cancelled 12 hours prior to the window close. I had to call Marriott support and they suggested we open a case and wait 3-5 days. Never once said sorry, nor would he call the hotel for me. I really miss the days of Starwood customer support and feeling valued @ Marriott Lurker , :-( So I had to call the hotel and they saw the mistake they made and voided out the charge.
