After a brawl started by drunken Russian-speaking guests, who accused me of attempts to visit their rooms (because I got into the same elevator) security guards have been called. They found me not in someone's room, but in the hotel lobby, got confused, demanded from me to go to sleep and when I laughed and refused (I am a grown-up and not obliged to go to bed when a non-policemen demand), they called the police, that, ultimately, refused to come. The whole fuss was caused by a receptionist, who was scared and overzealous at the same time. I went to bed much later that I intended to. Never again!
