The apartment has a nice location. When you arrive, make sure you ring the bell on the door with the blue, not the red number - they are like twenty five meters apart. Piero waited for us in the apartment and gave us the keys personally. He has good recommendations for the city.
You can use everything in the very well-equipped kitchen. You can do your laundry in the washing machine, then hang it to dry on the little terrace (beware though that travelers do also smoke on the terrace and your clothes might get some smell; ours didn't). The bed was clean and appropriately comfortable. There are lots of storage racks. The bathroom was clean and well-lit. A well-supplied supermarket is around the corner.
All in all it was a good place in a lively, but not tourist-crowded neighborhood.
