I changed rooms three times. The first night, the room temperature fell to 60 degrees as the window allowed cold air to blow into the room. In a different room on the second night, but the temperature could only go up to 60 degrees. The next day I switched rooms again and I needed to take a nap because I did not sleep well the prior two nights. Just as I fell asleep at about 4:00 PM, they started renovating the room next door - loud hammering and machine tool noises. The front desk essentially blew me off by letting me know that the hotel was being renovated and that there was nothing they could do. The next morning, in a room that was unexpectedly warm at 70 degrees, I was awakened by more hammering and machine tool noises at 8:30 AM. At the front desk on my way out, I complained only to be told that I should have just left if I did not like it, as if it were my fault. I will never stay at a Hilton property again, ever. This was the worse hotel experience of my life.
