Cesano Maderno rentals with hot tubs

The apartment's 'cooling system' was not airconditioning and did not cool below 27 degrees - this was way too hot. Worse though was the loud banging that occurred every 2.5 minutes for the last three nights. While the manager tried to remedy (it was a faulty water pump) it was not fixed and we could not sleep. i asked for money to be refunded for this time but was not answered. Unacceptable.
