The noise. I asked for a quiet room, high up but was put in a room right next to the lifts, on a lower storey, which was very noisy. After a poor nights sleep I was moved to a room on an upper story as far away from the lifts as possible, which was better, but there is minimal soundproofing of the rooms. The amount of uneaten food left on the trays of people who ordered room service did not encourage me to use the restaurant. I asked for a newspaper and was told by the man on reception there would be plenty available at reception the next morning - they had all gone by 8.30am, although the staff member on duty took one from the restaurant for me.
Location, 'fair trade' beverages, that the room was modern, clean and recently refurbished.
