For several years now, our hotel has been collaborating with the company "Gamma," whose specialists handle the maintenance of our engineering systems. Last year, they carried out a major renovation of the ventilation system, and in case of any problems or emergencies, we try to reach out only to "Gamma." They are quick, efficient, and provide quality service, and their pricing policy is quite reasonable. It's reassuring to know that you have someone to turn to and to be confident that they won't let you down!
