The location of this apartment is excellent, one block from the Duomo with a lovely view from the terrace. Note that the bells ring from 7am to midnight so if you are a light sleeper bring ear plugs. The apartment is clean and quiet and served us well for 4 people on a business trip. One room is in a mezzanine as per the pictures so does not have much privacy but was fine for us. There are no basic provisions provided (coffee, water etc) so you will need to bring your own.
The location is unbeatable though and so I would recommend staying here if you are looking for something central
