Ask the landlord or his agent.
People here can not see your appliance
The guy will be able to find the plug
The plug will be at the end of the cable - presumably the appliance is built-in rather than counter-top - the plug will be in a socket on the wall behind - low behind the plinth or in an adjacent cupboard - the installer will have needed to be able to plug it in - the plug will not be far away.
Good luck...
