You are in your personal office and you are working hard. You enjoy the view framed by the window, but slightly darkened. The only sound you hear is the music playing from the speakers. You open the window and take a breath of fresh air. You open the door and feel the wind, stronger than the air conditioner and much more pleasant. What more could you ask for? A cup of coffee from the kitchenette above the corridor, a pizza from the restaurant below, or just a glass of mineral water on the roof while enjoying the mountain view? Welcome to the headquarters of the Kalistratov group!
