Umberta's place was big and clean. It was like staying in a deluxe hotel room. We had our own bedroom and own bathroom separated from the rest of the house.
Her place was very close to the a Milan Metro station. It takes about 15min from her house to the main Duomo.
She was very accommodating on all aspects, from check-in to providing us breakfast every morning.
I would highly recommend her place if you plan on visiting Milan.
