My stay at Diana's was just as expected! She's very easy to talk to and everything was handled very fast and without any complications (arranging the check-in etc...). her appartement is super close to central milan, i guess you could consider her living in central milan. there's a metro station close by but we didn't even mind using it much since you can reach most of the central area by foot. to get a perspective it's about 20 minutes to get to the dome and even less to get to the first shopping streets, cafes are just around the corner. i'd recommend michetta, a place where u can get huuuuge sandwiches (vegetarian options available yey!) for a quick but good breakfast.
