We stayed two nights at Silvia's very nice apartment. It is located in a private area (doorman, one of many apartment buildings in a park area, 8th floor).
Silvia and her family (her husband, 2 girls, 2 cats) are extremely friendly, open-minded and cooperative with regard to check-in and check-out times. Communication through email was uncomplicated and quick. After we arrived they immediately gave us the keys and explained us how to get a free parking opportunity nearby. The whole apartment was very clean. Our room, the private bathroom as well as the linen and the towels were neat and clean. The bed was comfortable and big.
Silvia provided us with a map of Milano and explained us the most important places to go to. The apartment is nicely arranged and the terrace is huge and amazing.
To the metro station it is an about 15 minutes walk and after 15 more minutes you are in the city center (one way ticket: 1,50 Euro; day ticket: 4,50 Euro). The fact that the station is not so close cannot really be considered a "minus" since one can look up the distance on google maps before booking.
All in all, we had a nice time in Milano and can definitely recommend to stay at Silvia's apartment! Thanks for being so friendly and helpful :-) !
