We have not met Ilaria, so, we cannot make comments about her.
Instead we met Francesca who waited for us and was very pleasant and kindly answered to all our questions upon arrival (but also to all the other questions for which we used Whatsapp :-)).
Flat looks really nice and cozy and positioned close to Duomo; 10 - 15 minutes of an easy walk to Piazza Duomo.
For us it was perfect because we could reach center area of the city only by walking and we used metro + train only when we went to Bellagio on Lake Como and when coming / going to the airport. We preferred walking because you have the chance to see more things and you can stop and contemplate whatever place you find attractive.
You have couple of nice and good restaurants near by, also pasticeria places for having breakfast.
We recommend staying there and would like to come back if we'll have the chance to visit again Milan.
Grazie Francesca!
