The room is sufficiently large for two person and the view of the cathedral from the wide window is nice extremely at the night.
The apartment is totally clean and well furnished.
The local manager is cool.
The entrance is common with the other one but other facilities are private. Wifi access is shared with other guests and seems to have a limit of lines acceptable at the same time.
The only defect might be the location at the 5th floor without lift. When you arrive in front of the main entrance of the building, ring the bell of "Mangiavacchi" and climb the stairs to the last floor with baggage. The local manager never comes down to welcome and help you.
