We had a wonderful time in Milano, Stefano & Giovanna's accomodation strongly participated to it !
Very nice location in the heart of Milan's night life, acces to Duomo and city center by walk just take 20 to 25 min and is lovely.
The apartment in itself is freshly refurbished and very comfortable.
As for check-in / check-out, our hosts were very flexible.
I would recommend without hesitation.
