Piera's apartment is good for one person who wants to travel easily to Duomo di Milano and centrale station area. It takes only 15 mins to those sites without transferring to other lines.
The room is not spacious but has quite everything you need from olive oil to shampoo and kept clean. And the supermarket Connad is right at the corner of the apartment, you can easily access to buy anything you want in 3 mins once you want to.
There were two things I found a bit uncomfortable ; firstly, it has a balcony which opens to a big building construction site under operation regularly from 8AM to 4~5PM. So if you want to stay longer in bed till like 10 or 11 AM, it wouldn't be the ideal place.
Secondly, the check-in and check-out time is quite limited and unnegotiable. You can only check-out before 10AM on the day of leaving. period.
Other than those two, it was a pleasant stay overall.
