Heating excuse and poor service.
Totally agree with Lisa V below. we complained about the lack of heating every single day to be told the same excuse ( the building is regulated ) it was so cold outside we were wearing gloves. A porter eventually brought us two heaters after two days, one was broken and the other was covered in dust. after more complaining, which just spoils your holiday really doesn't it?, we were offered a free one night stay... Big deal we are hardly going to return across the Atlantic to stay in a cold dreary hotel for one night. 
We refused and were given a lunch credit of 200 usd. Sounds great until you realise the room cost us 700 usd per night and lunch is an average of 85 dollars each ( there were four people in my family so the credit wasn't enough).
The room was a good size and the beds were delightful with feather duvets and pillows but I do agree with other reviewers on the tired look of the rooms and the lack of attention to detail. If you want to stay here for the point of saying you've been then try not to pay too much and take a warm cardy.
One final point - the room service menu was missing in our folder and even after requesting it, it never arrived. This seems to be common so don't take anything from the mini bar, it's censored for weight, or it will cost you dearly and don't order tea in your room it is priced at eight dollars a cup!
