The cleaning staff! OMG! They enter your room without knocking, they vacuum at 7 am, they told us if we wated them to stop coming in our room we HAD to put out the do not disturb sign, otherwise they would keep coming in. Never have I encountered such a rude housekeeping staff. They left their vacuum cleaner in the middle of the hallway where you couldn't get by with your luggage, the list hors on and on.
