Piero is an excellent host. We had a great stay in his B&B.
The room and bathroom are large ( with great blinds that not only block the light but also noise), air conditioning excellent and the apartment is quiet and very clean.
Piero greeted us upon our arrival and recommended a very good Molisane restaurant. He was very responsive to our requests.
We walked everywhere although the subway is only couple minutes away. You can see Vatican museum from the room!
We definitely recommend Piero and we will stay again with him when we return to Rome.
