Vicenzo's place is really great and he is super nice! It's right beside the main train station plus you have easy access to the subway and shuttle buses to all 3 of Milan's airports. Making it super easy to travel anywhere you want! :)
I stayed at Vincenzo's place for 3 months its perfect for long stays and has all the amenities of home. Of course it would also be good for short visits due to its prime location. Vincenzo is also super nice and willing to help you out with any questions about the city and places to see or eat/drink at.
Bonus its also near by two weekday farmers markets!
Overall it was an amazing place to stay while I was working in Italy for 3 months and felt like I was right at home. :)
