The property never shared that they had an ongoing issue with their heating system. The room was freezing although the heating controls indicated that it should be warm. We called the front desk more than 4 times for help, but there was no answer. At 3:30a.m. we had to go to the front desk because the cold room temperature was unbearable. We had to wait for the cleaning person to find the front desk person, who told us that he would send maintenance to our room. The maintenance person arrived with a space heater for our room and explained that the main heater for the entire building had been broken for several days, which was later confirmed by hotel management. Our room cost $500 per night. At this price-point, and the quality that The Ritz-Carlton is supposed to represent, rooms should not have to have space heaters for warmth and the front desk personnel should be able to be reached 24-hours. Several years ago we had an issue at this exact hotel, and chose to try again since so much time passed. We made a HUGE mistake. Minimally, customers should be made aware of severe issues known to management prior to booking.
