I had an amazing experience at Antonia's apartment. The apartment is located in the heart of Brera in a luxury/high end building. The apartment is very well furnished, and offers everything you need. It seems living in Paris the way how is decorated the apartment.
It's great for families because you have close by Sempione park, and a couple of inside playground (in case of rain).
As soon as you step out from the building, there are great restaurants, bars, beautiful clothing stores, shoe stores, supermarkets, and the apartment is only 10 minutes walk distance from the Theater La Scala, via Monte Napoleone (one of the most prestigious streets for shopping) and Duomo.
The host, Antonia, is a beautiful person and very friendly. She helped me with everything I needed.
I would highly recommend this apartment.
