Our unit came with a bedroom that has no windows. So much for the 'mountain view' for which we paid extra.
Due to the lack of ventilation, the room got very warm. It was too hot to sleep in even without blankets. This wouldn't be such an issue if you could turn on the aircon, but management have deemed it too cold outside at night to activate it.
Their suggestion to deal with this issue? Open a window. Genius.
On top of this, you get a chorus of toilet, tap and fan noise from the neighbouring units to help you get to sleep.
