My partner and I stayed in this very nice appartement for 5 days. At our arrival, we've been greeted personally by our host who provided us with helpful information how to get around Milano. Whenever we had a question, we could ask via messenger and got an answer almost immediately.
There are two possible tram lines to reach the city centre within 20-30 minutes: Tram Line 1 and Tram Line 14. The tram stops are just around the corner, as well as the tabacco shop, where you purchase the tickets.
There's also a mini market on main street and a bigger Lidl about 10 minutes away by foot.
We usually had breakfast on the balcony and enjoyed our stay in this lovely appartement.
