Business meeting
Meeting room en c-3 was very poor. Not addapted to hold 40 people. Air conditionning not working well: Sometimes it was too cold and then too hot. Screen on the wall for the presentation is very small and was impossible to see the slides from the back of the room. 
Card key system for the elevator not working well. Several times the card was not properly read and it was impossible to stop at the wright floor. 
Once my key was not working in my room (18th floor) and needed to go to the reception to ask to reitinialise the key. 
the service on the restaurant is very poor. During one lunch, they did a mistake taking the order and we have to wait for almost one hour to get a salar and an hambourger... One of the person in the table never got his order. The only answer we have received it was "sorry sirs, the kitchen is fully booked ..."
For sure is the last time I organized a business meeting in this hotel. This was the worst experience in my life.
