Yes Les they are free ,they are built into the wardrobe in your room ,the new ones are digital in the newly refurbished rooms and the old ones are keys ,ask at the reception when you check in ,they will let you know which is which ,the instuctions are marked on them ,or on a card at the side , very easy to follow and operate . The weather in antalya just now is in the high nineties.
