Stayed one night in room number one. There was a loud humming noise coming from outside the bedroom window. I spoke to the hotel about this and was told the appliance would turn off at 9pm. We came back from the gig around 11.30pm and it was still running. It continued to turn on and off throughout the night. If we had been staying longer i would have complained and moved rooms. There are other reviews on here about noise issues in this hotel.
Staff very kind and helpful. Although I agree with energy saving, a small room with a window that does not open and the air conditioning that does not cool off at the desired temperature is not acceptable (a completely ineffective gradation is set). That the room was small was already evident from the booking, but the information on the restriction of opening the window for safety (a few cm) was completely hidden. Not exactly in the city center.
