Viviana is wonderful host and her place is truly amazing but definitely not for autumnal weather in Milan.
The apartment was cold every night. During day (and night) radiators didn't work at all. Theoretically the building manager was supposed to heat the apartment up to 21 degrees every day but in practice our towels were wet throughout the stay and the place were humid.
In addition... after a day in rather cold air you really want to wash in hot water but even that not always was certain.
