The one operated from the wall unit is controlled by the hotel and was shut off 4x in less than 24hrs of my first day of my stay. I complained several times, even at 4am when I was woken up by the heat in my room since the a/c was off, just fan blowing hot air.

Could you please translate this to English?
I did not liked the breakfast-organisation: filling up of empty buffet was slowly, finished tables where not quickly refreshed for new people coming to breakfast, coffee was not tasty, warm food was not decently kept warm.
