I was quite disappointed by the non working only one French TV Channel (TV5) and the queue and mess when trying to get to the breakfast area in the morning.
Also there is not a single shop wher to buy day to day useful goods (newspaper, book, smartphone products, sim cards, milk, rasor, etc..). For any need, one has to take a taxi.
Try to avoid queue in front of the reception desk by adding counters.
Your bar is in a closed room in which one cannot stay mote tha 10mn. You shoud open it and add windows.
