The apartment is really lovely. Not to big but it has nice furniture and enough space for four persons and includes everything you need for a city trip.
But what makes the apartment perfect is, how central it is located and how easy you can reach everything. Brera the part of Milan it is located, is really cute it has plenty of good restaurants and opportunities to go shopping. The distance to the Centre is really close and the next metro station is about 2 minutes away.
All in all we can say the apartment is really recommendable and will make your trip to Milan( btw an awesome city) a trip you will have in good memory.
