The front desk and all other services are very good but the room service is not 5 stars... For english there is no problem at all.
There is one super-market close to the hotel and many restaurent.
The spa is very relaxing, the sport area very complete, and the bar at the 25 floor is exceptional (very nice view).
To finish, regarding the price and the range of this hotel (5 stars), we can expect more about the quality of the room service, and the design of the bathroom ...
