I stayed in a suite in the South Tower (which is supposed to be the refurbished rooms - 3 years old). The suite was beautiful. It was very comfortable and had great amenties. Free bottled water, a loofah, and even a bathroom scale!
However, when I went to take a shower, the water wasn't hot. It wasn't even very warm. I called guest services and they said it was normal, especially because I was on the 20th floor. (The higher up you are, the more likely you won't have hot water.) They offered that I could change my room, but I was in a beautiful suite and didn't want to move rooms.
Then she told me to just let the water run until it turned hot. I let it run a full 15 - 20 minutes, which is expensive and wasteful. After 15 - 20 minutes, it was a good temperature. But it is pointless to stay in a suite and not have hot water!
I didn't like the food in the restaurant either. Not only was it extremely overpriced ($6 for a cup of soup), but the food wasn't anything special. When it was the Adam's Mark (before April 2008), they had an awesome restaurant on the top floor. Now, that's gone and the only restaurant is the mediocre one in the lobby.
On a positive note - the staff is wonderful and they offer free postcards with postage if you send them from the hotel's front desk.
I would recommend this hotel if you can get a good price, or if you need the great location.
