There is no noise insulation at all. I've been kept awake at night by my upstairs neighbor who comes in at dawn and the noisy warmer that thumps all night.
But the biggest problem is the bed bugs I found in my pillow when I woke up in the morning.
As soon as I woke up, I left the room without washing it.
I never want to go there again.
Luckily, it's been two weeks and I don't think the bugs have made it to our luggage.
(If it had, I would have had to consider legal action).
