I have enjoyed six visits to the Duke on the Test - four for meals and two for stays of several days. The staff have aways been friendly and helpful, the rooms have been excellent and the food awesome. So why have I given one star for service? Just before checking out today, a staff person whom I believe is the manager came in early to service the room. Her first words were "it is very hot in here" and proceeded to criticise me several times for having the radiators, asking me to turn them off then proceeded to turn off the one in the bathroom. We are senior citizens and feel the cold. I pointed out that the heat had only come on at 7:15am. She insisted the heat was on 24 hours. I corrected her and said the radiators in the bathroom and room had come on each day at 7:15am. The day time temperature the day before had been 15 degrees and the room was cold when I had taken my shower each morning. In 50 years of staying in many hotels internationally, I have never felt so humiliated as I felt this morning. Until that moment I would have given to hotel a 5 star for everything. Until I receive an apology I cannot recommend the hotel and will not be visiting again.
