The flat was fine, but we found Sonia to be incredibly rude and aggressive.
It was a hot weekend in Milan and we wanted to use the aircon but couldn't find the remote. When we asked Sonia for this she started shouting and screaming at us that it's not included, we needed to tell her in advance, and "what do you expect for 50 euros a night?!".
We pointed out to her that the description on her listing says "hot water, internet and air conditioning included". She then told us "Airbnb made a mistake" and slammed the phone down.
We are shocked at how badly she treats her guests, this was such a horrible experience compared to all the other Airbnb stays we have had. Needless to say it was an uncomfortable stay in her apartment as it is on the top floor in the former attic - the heat just doesn't escape.
Avoid - there are plenty of other apartments in the same area.
