I had a great experience at Marco's flat. The flat is very clean and has everything you need for a comfortable stay. The wifi works well. The flat is very close to the tram and subway lines that go directly to the city center, so it is very easy to visit all the famous places in Milan. There are groceries stores within a 5 minutes walk.
Marco is a great host. He was flexible with the check-in time and he was super with helping me with my luggage. I recommend his flat.
