The airbnb has several rooms with different amounts of beds. We stayed in room 3 which has a single bed and a full bed. The room also had AC which was really convenient in the summer heat. It is about 10 minutes walking from the central station or 5 minutes to the closest metro station (Sondrio). Check in was a breeze with the self-check in process. The kitchen was well stocked with complimentary snacks and coffee that were available for the guests. There was also wifi. The rooms and bathroom were clean and we enjoyed our stay. We would stay here again if we are back in Milan.
