Maroni is a very kind and cheerful person. He is very responsive and we had no problems to arrange a check-in window (although we were both very busy on that day). It is a pleasure to chat to him. Speaks both English and Italian fluently.
The room is simple, but clean. Same for the (shared) bathroom. The mattresses are fine, too. Kitchen can be used on request. So all easy.
The zone is not the greatest of Milan, but convenient if you have obligations in the North of the city. The metro stop of Comasina is 5 minutes away on foot. So if you don't mind the lack of elegance and you appreciate a host that cares for his guests , it is a very good place to stay!
