Just to update this:
Stayed at the Radisson Blu Carlton Hotel a couple of weeks back.
Booked a standard room directly with the hotel, then a friend noticed that the price was the same as the business room he booked with hotels.com. So at 1pm on the arrival day I cancelled, and rebooked on Hotels.com. Same price, and got breakfast and a business room.
When I checked in I asked if CC Gold would get me an upgrade, and was put into a Junior suite. It was a little bigger then my friends business room, and the bathroom had a dedicated shower cubicle as well as bath tub, apart from that, they were the same.
Listed amenities on a plaque in the room were: free newspaper daily, magazines weekly, and free pay per view tv and nespresso coffee. I never got a newspaper or magazine, and couldn't find a pay per view movie on TV... However, breakfast was excellent.
Wifi was ok to good. It took ages to connect to it, but most of the time it worked well.
Hotel is well located, by the old town, and next to the US embassy. If I were going back, I wouldn't hesitate to stay again.
