We stayed at the apartment with 6 people for 4 nights and were very happy with this decision! It was quite packed with all of us, but with 4 it is the perfect size!
However the place is actually bigger than it looks on the pictures and was very clean and we'll equiped. Almost everything you need is there: iron, washing machine, hair dryer, soap, cutlery, towels and so on.
We only had contact to Alex (a friend of Elisabetta) who was very caring and did his very best to make our stay perfect. We could always contact him and ask questions and he would help us.
The neighborhood is very nice, it's close to Navigli with a lot of restaurants, a supermarket is very close and the tram and metro are reachable by a short walk.
We would totally recommend this apartment! (:
