You are staying in a spare room of the owner’s apartment. The spare room comes with a small bathroom and a balcony. Upon arrival, you get a binder with some house rules and some tips for activities in Milan.
The apartment is outside the city center, but there is a tram stop nearby. The tram will bring you to the center in about 20 minutes.
The owner will go out of his way to make your stay as pleasant as possible, I really recommend this entire experience if you are looking for something affordable when staying in Milan.
