The property was Le Chateau Montebello.
I answered the survey on my stay letting them know what happened. Just got an answer, they apologized for the check-in experience and recognized that I should have get the upgraded room (and offered a complimentary upgrade for my next stay in the best room - noting that there is no suite here at all).
Overall the communication with the property was good (when they adjusted the non-refundable rate, and with their apology...), just a bad check-in experience will not make me angry against them, hopefully some training will happen at the front desk.
