The room was very clean, but it was freezing. It was 57 degrees and when we couldn’t get it warmer, we let the desk staff know. Someone came to put the heat on while we were out, but it was putting out cold air so still 57 n hour later. We let the desk know and an hour later we were still freezing with no response from the staff, so called again. That staff member didn’t know anything about it, but offered to switch us to another room. That room was also freezing, but the heat did work in that room so we got it to a comfortable temp. The wether was in the upper 70s outside so no reason for the room to be so cold. The fact that we were ignored for an hour when it was almost painful cold in the room definitely impacted how I see that hotel. I am sure that was not representative for all Doubletree, but it was a big disappointment.
