When I walked through the door and introduced myself, the clerk at the front desk looked rather blankly at me and said that he had no record of my reservation., even as I was showing it to him on my telephone. Nothing. He tried to ask which agent had made the reservation, and I kept fumbling for another answer other than "Hotels-dot- com". Eventually, he decided to give me a discount rate and a room, but I realized that I might've been out of luck on this one due to Hotels.com not following through (or letting me follow through with the reservation details.
Anyway the room was poorly lit, humid, and windowless except for the window which opened to the staircase inside the hotel. The service was basically friendly, but this was one of those rooms in which you realize that the lower price might not have been worth it, except for the proximity to the cathedral and Zocalo.
The lobby art was lovely, however, with some striking art and covered sport cars replacing any kind of guest amenities.
