We had a great stay at Claudio's apartment. As everyone else already said, he is an extraordinary host, he made everything possible to make us feel at home, even brought us fruit and water and other things to eat.
The apartment itself is beautiful, just like in the pictures, and you have everything you need. Claudio also prepared all sort of information about supermarkets and restaurants near by.
The neighborhood is very nice and very chic. Moscova metro station is very close, just a few minutes away, but you can have a nice walk to the Dome or Castello Sforzesco (15 minutes by foot).
We definitely recommend this apartment for your stay in Milan.
