Carmela is the friendliest host I've come accross. Very friendly, helpful and just enjoyable to talk with.
The room we stayed in was big and we were happy to have a fan in it since the temperatures go up a lot in Milan during the summer.
The kitchen is very small but it wasn't an issue for us.
We did all of Milan by foot; therefore the place is a little far from the city center. However, there is a supermarket (and a whole shopping mall) very close and an outdoor swimming pool about 20 min by foot.
