I can really recommend Andrea's place. His apartment is located between Milano Centrale (10 min. walk) and the Duomo (30 min. walk with nice shops and the Porto Venezia on the way). If you don't walk to walk you find two Metro stations (Lima and Loreto, 5 min. walk) to bring you to the city.
The flat is really nice and openly designed with modern furniture. Your room has a big, comfortable bed with french balcony and a clothes rail. In your own bathroom you will find towels and a hairdryer besides a big and modern shower. The flat and the room are very clean. If you want, you can have breakfast in the flat. The flat has also an air conditioner but it was not so warm when I was in Milano.
Andrea (and his friend as well!) is really nice, helpful and always open to have a little chat with you. I really enjoyed to talk to them before or after my day trip.
Check-in and -out were really flexible.
I really liked to stay at his place!
