We report 3 years of experiences with Swiss Facility operation at La Silla observatory. A brief overview of EULER -- the Swiss Ritchey-Chretien 120 cm telescope and of CORALIE -- the fibre-coupled, high-resolution Echelle spectrograph is given. We describe the design and the concept of the control system which mostly links together commercial hardware elements, free public software (Linux and GNU) and some key components built and fully controlled by Geneva Observatory. We focus on key elements, and we analyze various aspects of operation such as the efficiency, real-time requirements, calibration and maintenance and specific constraints of the astronomical observatory. We discuss the critical aspects of the automation of the operation, the conditions and the parameters which determine the degree of automation that can be achieved at the cost-effective level and we outline some possible improvement and future plans. We present the summary of scientific activity together with some scientific highlights.
