The apartment is beautiful with everything you need. The location could not be better - it really is in the centre of things and within easy walking distance of everything you will need to see in Milan. You will feel like a local in Milan. I recommend spending some time walking around Sforzesco Castle and park, just 5 minutes from the apartment. There are loads of very nice and affordable restaurants on the far side of this park that have a much more pleasant atmosphere than those near Duomo.
Davide was a great host and was very helpful. He answered all of our questions and was very easy to communicate with. We were a family of four adults and the apartment was perfect for us. I would highly recommend this apartment. It is excellent value for money which is rare in Milan. Also, the area felt very safe and we were very comfortable walking around both day and night.
