The problem in this hotel are the rooms. You can hear everything from your neighbor. And on my first night, after I changed one room, in the second one it was the same, because other guests in the second room were yelling and shouting. They had a party at 00:15 and they were not polite, because no one told them the normal rules if you sleep in a 4-star hotel. It means you can't shout and yell.
