We had very nice days in Milan. Especially because Alessandra's and Roberto's apartment was very clean, very cosy, very well equipped. There are nice and comfortable furniture, bed, sofa, etc.
Our hosts are very freindly, helpful and flexible people. They live next door, so you can contact them easily.
Public transportation is very good, especially to expo /fiero.
Do not miss to try the pizzeria " Il Molo", because it is very close to the apartment, has a delicious kitchen and a reasonable price - thank you for the recommendation!

So I really recommend this accomodation and the hosts. If its free, do not hesitate to book it! :)
