After I found the key through the key box, I entered the room by myself. This is an old-fashioned apartment, but the interior is newly renovated. But I think, in terms of details, it wasn't clean enough.
The apartment is large, with two separate bathrooms and enough room for three to four adults. The host provided us with refreshments and water.
To get to Milano downtown you have to take the metro line 5. It's only five minutes' walk away.
