Stayed there this week! The rooms are nicely furnished with the new Marriott room 'do', and there is a particularly well equipped gym.
Given the high price however, there were a few details that I felt should have been better attended to. My room wasn't as clean as it could have been (found some nasty stray hairs in the bathroom and in one of the blankets), and the Concierge lounge attendant was MIA along with some key breakfast items (i.e. no spoons for cereal, no napkins).
The price would have to drop significantly before I'd stay there again.
