The house is entered using a smart lock on the front door. When you send us your personal information (wich we need to register zou in local authorities as our guests) you will receive a message from us containing a generated 6-digit code. This code will be used to unlock or lock the front door. There is a dial on the smart lock. There you enter the code you received and after it you press the button with the key drawn on it (picture 1). If you have entered the correct code, you will hear the sound of the lock and then turn the lock counter-clockwise to unlock, or clockwise to lock the door.
