We stayed at Francesco's apartment for a week on our summer holiday. The best thing about this property is location. Very close to corso Buenos Ires shopping street and P. de Venezia station (with access to both Metro and suburban train) as well as tram station. Couple of supermarkets nearby as well as lots of restaurants and cafes.
Host was responsive although he tends to message in Italian (but tranalater app will help you.)
One thing that could've been better was the cleaniness, although people have different standards on this. We had to do ventilation and some cleaning on day 1 and had to wash all the kitchen stuff before using them.
But overall, OK size for a couple to stay and good value for money.
