There is not enough elevator. There is only 2 elevator for floor 2-18, however, even people for stories above are using those elevator while there is 2 elevator reserved for higher stories. Often we had to wait more than 10 minutes just to have space in an elevator!!!
Very well placed. The elevators are supposed to be renovated soon. It was difficult at times to reach our room or go to the lobby, however, once we noticed we could use the service elevators, all went smoothly
