The host is an unfair person. He was hiding the fact that heating system works with huge outages. Basically all the hight long heating batteries were could and in the day time only heating batteries in the premises were heat up. Also this premises has window frames with only the single windowpane and huge gaps (up to the 2 cm) along the all window frames perimeter. Warm air was leaking outside the premises through those gaps being replaces with continuous strong flow of could from the outside. This premises can't be offered for rent in the wintertime given that average weather in Milano is about zero in December. All the my relatives have got could spending one night under the described circumstances.
Also a dorman was deliberately misleading us that heating outages will be not more than two hours.
